Overall remarks and main impressions of 2004
2004 was the first full year of centre activity. CMA was established on March 1, 2003, but
entered the new centre premises half a year later. Although we reported on enthusiasm and
a good start in the 2003 report, we particularly emphasized the increased activity level at the
end of the year. The co-localization was vital to us, and in 2004 we have constantly grown,
both with respect to all possible key figures as well as in research quality. We are as
enthusiastic as ever, and we are grateful to the Research Council of Norway (RCN) and to our
host, the University of Oslo, for providing excellent conditions so that we may continue to
perform important research and research training.
We choose to emphasize the following as a main summary of 2004:
• We have obtained outstanding research results on many parts of our research plan. Our experience is that the plan
is well founded, and still serves as intended with challenging, but realistic goals.
• Since the very beginning we have focused on establishing new research relations, and throughout the whole 2004
we have used incentives to encourage research activities that support our research plan. New CMA members have
been employed with preferences to the focused areas of the research plan, and the total scientific activity of the
centre is well adjusted to the the plan.
• Several seminar series and workshops have been arranged with extensive external participation. Numerous guests
have been received. CMA members have participated and contributed to research events in all parts of the world.
We have entered national and international binding cooperation. Hence we regard ourselves highly active and
visible on the national and international scene of mathematics and its applications.
• The cooperation with SINTEF as active partner on more industrial related research is well established and fruitful to
both parts.
• The relationship to our host departments, faculty, and institution is very good. We feel well integrated. Efficient
administrative support is ensured by utilizing the existing university organization.
• We outperform all financial estimates of the original plan, and we have reached a revenue/cost balance in 2004.
Total revenues in 2004 were MNOK 38,5 compared to 31,8 in the original budgets. Conservatively estimated
revenues for 2005 are adjusted to MNOK 40,0 (compared to 33,5 in the original budget).
• Several successes in generating new activity/projects are described in this report. We will specifically highlight the
YFF-grant of our Professor Kenneth Karlsen, and the «Transfer of Knowledge»-project «CENS-CMA» (within EU’s
framework programme 6) in cooperation with Centre of Nonlinear Studies in Estonia.
Selected research highlights
out to deviate dramatically from the optimal portfolio for a trader without such information about the future (an
honest trader, for short). Thus the trading strategy of an insider is often quite conspicuous if the insider trades optimally.
This knowledge makes it easier to detect and prove when insider trading has taken place.
Continuously operated clarifier-thickener units for the solid-liquid separation of suspensions are widely used in chemical
engineering, mineral processing, the pulp-and paper and food industries, and wastewater treatment. Professor Kenneth
Karlsen is involved in an ongoing program related to the formulation and analysis of new mathematical models for
continuous sedimentation-consolidation processes of flocculated suspensions in clarifier thickener units. Many results
have already been obtained and will appear in various international journals, and in time they will be integrated in real
industry activities.
Postdoc fellow Snorre Christiansen has established a close connection between the finite element spaces used in
electromagnetics and the Regge calculus proposed for approximations of Einstein’s equations of general relativity.
Computational relativity is one of the most challenging numerical problems of our time. Christiansen’s paper makes
an unexpected connection between Regge calculus and the much better understood theory of Whitney forms. The
use of Whitney forms in computational electromagnetics has revolutionized the field. There is reason to hope that the
connection Christiansen has obtained will be an important step towards a similar revolution in computational relativity.
Main challenges at the beginning of 2005
The main challenge and first priority is to implement even more interdisciplinary research according to our research
plan. In addition we intend to contribute significantly to the development of Norwegian research in our areas. Our aim
is to increase the level of national and international collaborations.
A main concern is the renewal of our project portfolio, especially with respect to individual grants. Presently such grants
seem to become harder to obtain within the RCN-system, and the academic profile of CMA hardly fits the larger
programmes of RCN. We have joined forces with the rest of the mathematical community of Norway in order to work
towards the establishment of a national programme dedicated to mathematics and its numerous applications.
Furthermore we are constantly working towards the EU system and its different Marie Curie instruments, which also
may provide training positions. Training of new researchers is a main goal of CMA, and does not interfere with the core
research of the centre. On the contrary, the more fellows entering the CMA community, the more research will be
carried out.
In 2004 we have improved on media visibility with appearances in radio, newspapers, and magazines, but still these
efforts need more focus.
The paper «Mean value coordinates» by Michael Floater, published in the March 2003 issue of CAGD (mentioned in
last year’s report) was selected by International Science Indicators as a «Fast Breaking Paper» in the field of Computer
Science in December 2004. Every two months the ISI select one highly cited paper from each of 22 scientific fields out
of the articles in their database of over 6,500 journals. The paper offers a fast and safe method – a simple, but truly
novel discovery - for computing a parametric representation of a surface initially given as a mesh of triangles. This is a
crucial step in, for example, reverse engineering (converting a cloud of measured sample points to a CAD model) and
in texture mapping for visualization in computer graphics. Other researchers use it either directly or as the start point
for more sophisticated methods.
Professor Bernt Øksendal and the stochastic analysis group of CMA have developed several new results in the theory
of mathematical finance, and thereby received a lot of international attention. Of particular interest has been new
knowledge on insider trading in financial markets. We now know that even a small amount of information about, say,
the future values of a stock can be used to obtain a huge profit for a trader with access to such information (an insider,
for short). Moreover, in some cases the optimal portfolio for an insider can be computed explicitly, and often it turns

Introduction, with a focus on the interdisciplinary aspects
The main goal of the research activity of CMA is to create a national research centre with an atmosphere where
the participants continue to do first rate research in the four main areas of the centre, i.e. geometry, stochastic
analysis, differential equations, and applications in physical sciences. The activity in physical sciences is focused around
computational astrophysics and computational quantum mechanics. However, in addition to preserving the high level
activity in these areas, a central idea behind the establishment of the CMA is to create new interdisciplinary research
activity based on the interplay between these areas. Examples are interdisciplinary research activities where we focus
on the interplay between
i)
ii)
iii)
iv)
v)
vi)
computational geometry and algebraic/differential geometry
computational geometry and differential equations
stochastic analysis (specifically mathematical finance) and differential equations
stochastic analysis (specifically mathematical finance) and physical sciences
differential equations and computational quantum mechanics.
differential equations and astrophysics
During 2003 and 2004 we have carried out a number of actions to stimulate such activity. First of all, in the
announcements for new PhD and postdoc positions, we have given candidates with an academic profile and interests
in the directions of such combined topics high priority. Based on the same reasoning we have also encouraged
the PhD fellows to select their two supervisors from different research groups. As a consequence, most of the
candidates which have been hired for these positions are working on interdisciplinary topics. Furthermore, many of our
workshops and seminars have been dedicated to topics which we consider strategic for generating the desired new
research activity. Examples are workshops on numerical astrophysics, computational finance and physics, multiscale
modeling, and a workshop covering the interface between mathematical properties of the Schroedinger equation and
quantum mechanics. In addition we have run a weekly seminar, the CMA seminar, were we have focused on possible
interdisciplinary research problems. All these events are further described in the sections below
Of course not all the scientific results reported below reflect the CMA focus on interdisciplinary research. It takes time
to build new research activity, and at the same time it is important that activity in well established fields is maintained.
However, especially on i), iii), and v) in the list above we see a significant increased activity, and the first real research
results have appeared. Also for ii) and iv) collaborations are established, events have taken place, or fellows are
engaged, but results and reports are still premature. In 2005 we will pursue initiatives towards establishing real new
activity in vi), in addition to the continued focus on the areas above.

Piene, her PhD students Pål Hermunn Johansen and Heidi Mork, and her two master degree students, have all been
continuing the study of the topology and singularities of real algebraic curves and surfaces, with an eye towards
applications in CAGD. Preliminary results have been presented at workshops and in lectures, and as deliverables to the
GAIA II project.
Piene spent one month at MSRI in Berkeley, participating in the programs Differential Geometry and Topological
Aspects of Real Algebraic Geometry.
Tor Dokken has continued the work on approximate algebraic methods within the GAIA II project. The original
approach to approximate implicitization was based on products of polynomials represented in bases that are a partition
of unity over the domain of interest. The theory has now been extended by Jan B. Thomassen and Dokken to include
a sampling based approach and weak approximate implicitization based on integration over the domain of interest.
Together with Pål Hermunn Johansen, Dokken has also developed a theory for foot point calculations for rational
parametric surfaces by moving algebraic surfaces. This is a result where insight from algebraic geometry aids both
understanding and development of new and promising approaches to challenging CAGD-problems.
SINTEF has been granted funding by The Research Council of Norway for the strategic research project «Graphics
Hardware as a High-End Computational Resource» under contract number 158911/I30 for the period 2004-2007. Tor
Dokken is the project leader, and Michael Floater supervises two PhD students that are funded by the project. Results
from the first year of the project are very promising with speed-up factors of 20 for typical algorithms implementing
forward difference schemes for partial differential equations. A 2 day workshop on the potential of the GPU took place
at CMA in November 2004 with 40 participants representing both academia and industry.
Michael Floater has begun an investigation of the effect of parameterization on parametric curve fitting. Roughly
speaking, the main result is that chord lengths are fine for low degrees, but not accurate enough for higher degrees.
More precisely, the chordal parameterization gives full approximation order when fitting polynomials of degree at most
three. This result has been extended in two different ways: (1) the result for cubic polynomials extends to C2 cubic
spline interpolation, i.e., chordal parameterization gives fourth order accuracy; and (2) using an iterative algorithm, a
parameterization can be computed which supports polynomial interpolation of any degree.
The paper «Mean value coordinates» by Michael Floater, published in the March 2003 issue of CAGD (mentioned
in last year’s report), was selected by International Science Indicators as the «Fast Breaking Paper» in the field of
Computer Science in December 2004. For further information and a «mini-interview», see www.esi-topics.com/fbp/
fbp-december2004.html
Main scientific results
The two postdocs Tatiana and Vitaly Surazhsky have continued their work in geometric modelling. They have
developed a new method for sampling planar curves based on an analysis of curvature and an exact method for
computing geodesic curves on triangular meshes. The latter is being published jointly with Hugues Hoppe and Steven
Gortler.
Geometry
The activity in geometry is focused around geometric modelling. Many scientific and industrial problems require a digital
description of geometry. The research at CMA in this area is a based on combining techniques and theory from splines and
mesh based modelling, algebraic methods and differential equation methods.
Atgeirr Flø Rasmussen and Michael Floater have jointly explored the use of PDE’s to compute surface parameterizations
with certain desirable properties. They have also developed a general algorithm for estimating the length of a
parametric curve using only point evaluations, which would be an advantage if derivatives were expensive or impossible
to compute.
Together with representatives from the European network in algebraic geometry, EAGER, Ragni Piene and the Nice
partners from the EU-funded IST-FET GAIA II project organized the conference Algebraic Geometry and Algebraic
Modeling that took place in Nice in September. The aim of the conference was to present new results, algorithms,
developments and applications of effective algebraic geometry in geometric modelling. The proceedings from the
conference will be published in 2005.
Regarding mesh-based modelling, Christopher Dyken and Michael Floater have written a preprint about their discovery
of a simple method of determining a unique choice among all possible Delaunay triangulations of a given set of points in
the plane. This method could potentially have several applications, but one at least is to triangulation-based methods for
compressing digital images in which the uniqueness of triangulations is critical to minimizing the amount of data needed
to represent the approximate image.

The research activity of Tom Lyche has been on condition numbers for the Bernstein-Bézier basis using mixed norms,
and Hermite Subdivision for constructing curves and surfaces with prescribed shapes.
Lyche and Floater organized the CMA-sponsored workshop on Subdivision Curves and Surfaces during 2-3 Dec. 2004,
with about 40 participants from Norway and abroad.
Tom Lyche was co-editor of «From Object-Orientation to Formal Methods, Essays in Memory of Ole-Johan
Dahl» published by Springer. This book was reviewed in the February 2005 issue of «The Times Higher Education
Supplement».
Trond Brenna defended his PhD dissertation «Data Reduction on Cubical and Spherical Domains Using High
Dimensional Tensor Splines».
An important research topic for Knut Mørken in 2004 was zeros of spline functions. Together with PhD-student (now
post. doc.) Martin Reimers, he developed a new method for finding zeros of univariate spline functions, and gave a
detailed analysis of its convergence. The method may be viewed as a discrete version of Newton’s method. It converges
just as quickly as (and often more quickly than) the classical Newton’s method, but requires no starting values. Since
polynomials are special cases of splines, this also provides a new method for finding real zeros of polynomials. Work
continues to try and exploit this method for finding zeros of tensor product spline surfaces.
Reimers defended his PhD dissertation «Topics in Mesh Based modelling» in September. In addition to the work on
zeros of splines, the thesis covered a variety of topics including wavelets, parameterization, simulations of airflow in the
nose and a new algorithm for estimating geodesic distance on triangular meshes.
In 2004, Mørken has also started collaboration with the Interventional Centre at the National Hospital in Oslo. The
aim of the project is to develop new techniques for visualising human organs which can aid in developing new surgery
techniques. A major challenge is to efficiently unite data from different sources like MR, CT, X-ray and video to provide
a better view of an organ than each one of these sources can provide on their own.
Together with Morten Dæhlen from the Department of Informatics, Marie-Laurence Mazure from Université Joseph
Fourier (Grenoble, France) and Larry Schumaker from Vanderbilt University (USA), Mørken organised the Sixth
International Conference on Mathematical Methods in CAGD that took place in Tromsø in July. The conference was
attended by 140 scientists from all over the world and was also a celebration of Tom Lyche’s sixtieth birthday.
The research activity in Linear algebra and optimization is led by Geir Dahl and falls into the two areas Combinatorial
matrix theory (A), and Discrete optimization (B). In area A, Truls Flatberg defended his PhD thesis «Majorization and
optimization related to graphs and (0,1)-matrices». The thesis, and some joint papers with Dahl, focus on combinatorial
optimization problems in discrete tomography, an active research area related to the analysis of digitized images.
Flatberg and Dahl have also simplified a proof of some results for graphical sequences. Dahl has studied properties of
certain classes of doubly stochastic matrices and related polytopes, as well as the notion of majorization in connection
with distances in trees.
In area B, Njål Foldnes defended his PhD thesis «Polyhedra and algorithms for some knapsack problems and hopconstrained paths». The thesis contains a study of classes of knapsack polytopes and is motivated by applications in
mobile communication systems. One of the published papers, which is joint work with Dahl and L.Gouveia, presents
new completeness results for hop-constrained walk polytopes. Dahl has also co-authored a survey paper on hopconstrained spanning tree problems.
Stochastic Analysis
The research at CMA in stochastic analysis is closely related to applications in finance. Focused research topics are stochastic
differential equations and stochastic control theory. The development of numerical methods for such problems is planned to be
a central issue.
8
The stochastic analysis group,
(i) organized the 11th Workshop on Mathematics and Economics in Oslo in
(ii) co-organized the workshop «New Techniques in Stochastic Analysis» held in Espoo, Finland 16-18 August 2004 and of the
(iii) co-organized the SAMSA Conference 2004, held in Polokwane, South Africa 29 November-2 December 2004.
The research of CMA in stochastic analysis has been focused on stochastic partial differential equations, various types of
stochastic control and Malliavin calculus for Lévy processes, and their applications, especially to finance.
Fred Espen Benth and Jurate Saltyte-Benth have analyzed temperature data collected from several Norwegian cities,
and propose a mean-reverting stochastic process with a seasonal volatility to model the dynamics. The suggested
model is simple enough to provide explicit expression for interesting forwards and options written on temperature
like CAT-forwards and European call and put options on these. At the same time, the model is able to capture most
of the observed stylized facts, most notably, the seasonality in the squared residuals after regressing the temperatures.
The work is now under generalization to include pricing of HDD and CDD forwards and options on these. A spatial
version of the model is also under investigation. The work was accepted for presentation on the 3rd World Bachelier
Conference on Mathematical Finance.
Fred Espen Benth and Thilo Meyer-Brandis have calculated explicitly the density process for the minimal entropy
martingale measure in a non-Gaussian Ornstein-Uhlenbeck stochastic volatility model proposed by Barndorff-Nielsen
and Shephard. An integro-Black & Scholes equations is derived yielding the price of options. To solve this equation, one
needs to resort to numerical methods, currently under investigation by Groth.
Fred Espen Benth and Kenneth Hvistendahl Karlsen have considered a stochastic portfolio problem of the classical
Merton type, where the risky asset follows an exponential mean-reversion process rather than a geometric Brownian
motion. A classical solution of the portfolio problem is obtained and verified for a time interval depending on the
parameters. Outside this interval, there is not enough regularity to verify the solution.
Giulia Di Nunno has been working on stochastic anticipating Malliavin/Skorohod calculus for Levy random fields on a
general topological space. Levy random fields are a very general set up which includes as special cases the Brownian
sheet and Levy processes (and thus both the Brownian motion and the compensated Poisson random measures), all
widely used in applications to finance and to physics. She has introduced a class of orthogonal polynomials, studied
their properties and used them in the construction of the integral and derivative operators. Particularly interesting
and completely innovative are two suggested versions of these operators in which,on one side, the structure of the
Skorohod integral can be recognized as limit of certain Riemann sums and, on the other side, the anticipative structure
of the Malliavin derivative is shown.
Giulia Di Nunno, Thilo Meyer-Brandis, Bernt Øksendal and Frank Proske have worked on the modeling of insider
trading via forward integration. In particular they have extended the techniques of forward calculus, which were
originally designed for Brownian motion, to Levy processes.
Inga B. Eide and Giulia Di Nunno have been working on a version of the fundamental theorem of asset pricing for
continuous time market models in which some stochastic bounds for the probability density are considered a priori.
This reinforced concept of equivalency of probability measures finds applications in the modeling of the pricing of
insurance products via financial methods.
Tom Lindstrm has worked on Levy processes from a nonstandard point of view. He has shown how to construct
a hyperfinite Levy process as an infinitesimal random walk and developed the basic theory for such processes. The
standard parts of the hyperfinite Levy processes are the classical Levy processes.
Klara Hveberg has been working on self-homeomorphic fractals. She has shown that a number of seemingly
different separation properties actually coincide, and she has also developed several methods for constructing selfhomeomorphic fractals.
9
Bernt Øksendal, Francesca Biagini, Agnés Sulem and Naomi Wallner have studied the Malliavin calculus and white noise
theory for fractional Brownian motion. Such processes are interesting because of their many applications in finance
(weather derivatives, electricity pricing) and other areas (e.g. turbulence).
Bernt Øksendal and Agnés Sulem have continued their cooperation on two research areas:
(i) The use of anticipative calculus and Malliavin calculus in problems of optimal stochastic control with partial
information in an anticipating environment (e.g. a market influenced by insiders) and
(ii) various types of stochastic control problems (including optimal stopping, impulse control and singular control) for
jump diffusions and their applications, mainly to finance.
Giulia Di Nunno, Bernt Øksendal and Frank Proske have developed a white noise theory for Levy processes and for
compensated Poisson random measures. The results are applied to minimal variance hedging in the incomplete markets
driven by Levy processes.
Nils Christian Framstad, Bernt Øksendal and AgnésSulem have obtained a maximum principle for optimal control for
jump diffusions. The results are applied to solve mean-variance hedging problems in finance.
Arne Løkka, Yaozhong Hu, Bernt Øksendal, Frank Proske and Tusheng Zhang have studied two different types of
stochastic partial differential equations:
(i) Those driven by Levy space-time white noise [LØP] and
(ii) those driven by multi-parameter fractional white noise [HØZ]
In both cases the theory is used to solve certain stochastic partial differential equations explicitly.
Xue-Cheng Tai’s work work has been focused on the use of partial differential equations and level set methods for
image processing and inverse problems. For example, in joint papers with Tony Chan and Stanley Osher, UCLA, Los
Angeles, and others, he has performed various studies of the effect of nonlinear regularization procedures for these
problems. Per Christian Moan is working on a time averaging theory for discrete dynamical systems. In particular, he has
studied the relation between geometry preservation of discrete schemes and their conservation properties.
Currently we can divide the research activity of H. Holden, K. H. Karlsen, and N. H. Risebro, together with G. M.
Coclite and M. Bendahmane, into 6 main themes.
Degenerate parabolic equations:
Bendahmane and Karlsen have introduced a new notion of entropy solution and proved an existence and uniqueness
result for doubly nonlinear anisotropic degenerate parabolic equations, supplemented with an initial condition and a
homogeneous Dirichlet boundary condition. Because of the considered generality, solutions will in general develop
discontinuities, even when the initial date are smooth. Hence it becomes necessary to interpret the equation in the
weak sense. However, an additional selection criterion, a so-called entropy condition, is needed to single out a unique
weak solution. .
Sure Mataramvura, Bernt Øksendal and Frank Proske have studied the Donsker delta function for Levy processes and
used it to obtain the chaos expansion of local time for such processes. The local time often appears in the solution of
singular stochastic control problems.
With G.-Q. Chen at Northwestern University, Karlsen has studied the existence and uniqueness of discontinuous
entropy solutions to quasilinear anisotropic degenerate parabolic equations with explicit (t, x)–dependence. A wellposedness theory for the Cauchy problem for such degenerate equations has been established via Kruˇzkov’s device of
doubling variables. Moreover, we have established a continuous dependence estimate for perturbations of the diffusion
and convection functions. This is the first time such a well-posedness theory (in classes of discontinuous functions) is
obtained when the second order operator contains an explicit spatial dependence.
The big European research project «Advanced Mathematical Methods in Finance» (AmMaMeF), involving 15 European
countries, was approved by the European Science Foundation (ESF) in 2004 and it will start in 2005. The stochastic
analysis group at CMA is heavily involved in this project, in which Bernt Øksendal og Giulia Di Nunno are elected
project Chair and project co-Chair, respectively.
With Coclite, Holden has studied stability of solutions of quasilinear parabolic equations. The goal is to obtain explicit
norm estimates of differences between two solutions when one varies the initial data as well as the parameters in
the equations. Partial results have existed, but Coclite and Holden provide explicit bounds in the general quasilinear,
multidimensional case.
Differential Equations
Mathematical modelling and numerical simulations have become an indispensable tool in science and engineering. Partial
differential equations are one of the most fundamental tools in constructing such models. The activity in differential
equations at CMA is devoted to theoretical aspects of partial differential equations and on the numerical treatment of
such problems.
A common theme of the work of Snorre Christiansen, Runhild Klausen, and Ragnar Winther is numerical methods
for partial differential equations, in particular finite element methods, mixed methods and finite volume schemes.
As a continuation of his earlier work, Christiansen has developed a discrete Fredholm theory to obtain convergence
estimates for approximations of the integral equations from electromagnetics close to resonant frequencies. In another
fascinating paper he has established a close connection between finite element spaces design for electromagnetics,
i.e. the Nedelec spaces, and the Regge calculus developed for discretizing the Einstein’s equations of general relativity.
Another link to Einstein’s equations can be found in Christiansen’s joint work with Winther on the Yang-Mills system,
where approximate constraint preservation for various discrete schemes is studied.
Runhild Klausen holds a joint post.doc. position at CMA and another Norwegian centre of excellence, Centre for
Integrated Petroleum Research (CIPR), at the University of Bergen. The idea behind the cooperation between the
two centres is to join forces on problems related to partial differential equations in the petroleum activity. Klausen’s
10
research, partly joint with researchers at CIPR and with Tom Russel, University of Colorado, Denver, has lead to
improved understanding of some of the locally conservative discretization schemes developed by the oil industry.
Discontinuous flux problems/sedimentation models:
Continuously operated clarifier-thickener units for the solid-liquid separation of suspensions are widely used in chemical
engineering, mineral processing, the pulp-and-paper and food industries, and wastewater treatment. With R. Bürger at
the University of Stuttgart and J. D. Towers at Mira Costa College (San Diego), Karlsen has formulated and analyzed a
new mathematical model for continuous sedimentation-consolidation processes of flocculated suspensions in clarifierthickener units. The model consists of scalar, strongly degenerate parabolic equation in which both the convective and
diffusion fluxes depend on parameters that are discontinuous functions of the depth variable. The initial value problem
for this equation is analyzed. We have also introduced a simple finite-difference scheme and proved its convergence to
a weak solution that satisfies a certain entropy condition.
Shallow water equations of Camassa-Holm type:
Coclite, Holden, and Karlsen have studied existence and uniqueness of solutions of the so-called generalized
hyperelastic-rod equation. This equation can be considered a generalization of the Camassa-Holm equation. The
Camassa-Holm equation has many special properties, for instance it is completely integrable, that do not carry over
to the hyperelastic-rod equation. In a special case, the equation has been used by Dai as a model for small amplitude
radial deformation waves in cylindrical compressible hyperelastic rods. Coclite, Holden, and Karlsen introduce a
regularized version of the generalized equation, and show existence and uniqueness of solutions of the regularized
equation. Furthermore, they show that the solution is stable when the regularization vanishes.
11
Holden has with X. Raynaud of the Norwegian University of Science and Technology showed how to obtain solutions
of the Camassa-Holm equation as limits of a particular finite difference scheme. Their result covers the period case
when the initial data gives a global solution. No rigorous numerical methods have been known for this equation prior
to this result. Raynaud and Holden have also shown how solutions of the Camassa-Holm equation can be obtained as
limits of multipeakon solutions when the number of peakons increase. This result also provides an efficient numerical
method to compute the solution, and is valid in the case where a global solution exists.
Nonlinear Hammerstein type equations:
In collaboration with Prof M. M. Coclite (University of Bari-Italy), Coclite worked on Dirichlet problems for
integrodifferential equations of elliptic type with singular nonlinear term in the origin. These problems can be rewritten
as integral nonlinear equations of Hammerstein type.These ones arise, more or less directly, in a variety of settings:
semilinear boundary value problems with a nonlinear term depending on the reciprocal of the solution, mathematical
models of signal theory, ecological models, continuous extension of the results on double stochastic matrices, and
Boussinesq’s equation in filtration theory.
Integro-partial differential equations/stochastic control theory/finance:
With E. R. Jakobsen of the Norwegian University of Science and Technology, Karlsen has developed a very general
framework for deriving continuous dependence estimates for possibly polynomially growing viscosity solutions of fully
nonlinear degenerate parabolic integro-PDEs. This framework has been used to provide explicit estimates for the
continuous dependence on the coefficients and the «Levy measure» in the Bellman/Isaacs integro-PDEs arising in
stochastic control/differential games. Moreover, these explicit estimates are used to prove regularity results and rates of
convergence for some singular perturbation problems. The results have also been applied to some integro PDEs arising
when pricing European/American options in an incomplete stock market driven by a geometric Levy process. Many of
the results obtained are completely new, even in the convex case where stochastic control theory probably provides an
alternative to our pure PDE methods.
With E. R. Jakobsen, Karlsen has also proved error estimates for a commonly used operator splitting method for
degenerate parabolic equations with source terms, which are equations that are related to Bellman’s equation from
optimal stochastic control theory. The error estimates are derived within the framework of viscosity solutions, are thus
robust with respect to the (lack of ) regularity of the solutions.
Benth and Karlsen have studied Merton’s classical portfolio optimization problem for an investor who can invest in
a risk-free bond and a stock, so that expected utility from terminal wealth is maximized. The special feature of the
problem studied is the use of Schwartz mean-reversion model for the dynamics of the risky asset. This gives raise to a
Bellman equation which we solve to obtain the explicit trading strategy and an expression for the value function.
With L. Holden of the Norwegian Computing Center and S. Holden of the Dept. of Economy at the University of
Oslo, H. Holden has completed a study of a model in differential games. The system can be considered as a model
for contract adjustment under uncertainty between two players. At each point in time of the players can demand a
contract negotation, readjusting the payment according to an underlying stochastic process. Adjusting the payment
carries an exogenous fee to both players. The existence of Nash equilibria is discussed, and numerical calculations are
included.
Harmonic maps:
Bendahmane and Karlsen have studied anisotropic nonlinear elliptic systems with measure data and anisotropic harmonic
maps into spheres. Existence results for distributional solutions of anisotropic nonlinear elliptic systems with a measure
valued right-hand side are provided. The functional setting involves anisotropic Sobolev spaces and weak Lebesgue
(Marcinkiewicz) spaces. Some maximal regularity and uniqueness results are proved as well. The obtained results are
applied, along with an anisotropic variant of the div-curl lemma in the Hardy one space, to prove that the space of
anisotropic harmonic maps into spheres is compact in the weak topology of the relevant anisotropic Sobolev space.

Quantum Mechanics
The starting point for all of our investigations is the development of appropriate techniques for studying systems of many
interacting particles, so-called many-body methods. The systems of interest span most of the fields in physics covered by nonrelativistic quantum mechanics, that is atomic, molecular, nuclear and solid-state physics and the physics of quantum liquids.
In total CMA has organized four different workshops and meetings during 2004 related to computational aspects of
quantum mechanics. Last year marked also the establishment of a large collaboration on computational many-body
physics between CMA and the department of Physics in Oslo and Oak Ridge National Lab (ORNL) and Michigan
State University (MSU) in the USA. This collaboration counts at presently 15 researchers in Norway and the USA,
with several PhD students and master students and spans from quantum chemistry, to nuclear many-body physics and
computational science. David Dean of ORNL was appointed as Prof II at CMA, while Hjorth-Jensen is adjunct Professor
at MSU, East Lansing since june 2004. More detailed information on these activities are summarized below.
The methods we study are
1) Variational and diffusional Monte Carlo methods.
2) The solution of the time-dependent Schroedinger equation using finite element methods.
3) New algorithms for many-body systems based on concepts from quantum computing and quantum information theory.
4) Non-perturbative resummation of large classes of diagrams in many-body physics, especially coupled cluster and
parquet diagrams techniques.
5) Large scale diagonalization techniques, with special emphasis on the nuclear many-body problem.
6) Many-body perturbative approaches to weakly bound systems.
The three first research areas given here are all partly new activities in Oslo, where several master students and CMA
fellows so far are doing a major part of the work. Focusing on these research fields at the boarder line between physics,
mathematics, and partly chemistry, reflects the research plan of the CMA, and represents a joint activity between the
quantum mechanics group and the CMA groups in stochastic analysis and differential equations.
Variational (VMC) and diffusional (DMC) Monte Carlo methods
Four students obatined their master degrees last year and all four have continued with PhD studies in Oslo or Bergen.
Topics which has been studied include ground state of atoms with charge Z < 40, ground state properties of quantum
dots with up to 20 electrons, Bose-Einstein condensation of dilute atomic gases with the inclusion of vortices, and
ground state of light nuclei. Of interest for our research program is development of Monte Carlo codes in order to
handle systems of interest for applications in materials science and nano-technology. A workshop on Computational
finance and physics, with an emphasis on Monte Carlo methods was held at CMA in march 2004.
The solution of the time-dependent Schroedinger equation using finite element methods.
Simen Kvaal (master thesis march 2004) started as a PhD student at the CMA in may 2004. The focus of his thesis
is on studies of finite element methods applied to the solution of the time-dependent Schroedinger equation. This
is currently of great interest due to the developments in ion-trap experiments and the capability to isolate electrons
(quantum dots) or atoms in small confined regions of space. This field has important consequences for future
development of quantum circuits and our basic understanding of the quantum dynamics of single trapped particles.
New algorithms for many-body systems based on concepts from quantum computing and quantum information theory.
Eirik Ovrum is a PhD student at CMA. The topic of his thesis is to implement algorithms from quantum information
theory in order to study their suitability for dealing with many-body systems. This is a collaboration with the Jon Magne
Leinaas at theory group at the Department of Physics at the UiO.
Non-perturbative resummation of large classes of diagrams in many-body physics
This project defines the collaboration between Oak-Ridge national laboratory, the UiO and Michigan State University at
East Lansing.
13
This project has already resulted in several articles and invited contributions to conferences and workshops, amongst
these the International Nuclear Physics conference held in Gothenburg in 2004 (INPC2004) and the international
conference on Exotic Nuclei and Atomic Masses (ENAM04) held in Pine Mountain, Georgia, USA. The project centers
on the coupled cluster method and the people involved are
1) ORNL : Prof. David Dean (also adjunct professor at CMA), Drs. Thomas Papenbrock, David Bernholt (Computer
Science division) and Robert Harrison (Computational Chemistry)
2) Michigan State University, Department of Chemistry: Prof. Piotr Piecuch and Drs. Karol Kowalski and Marta Wloch
and graduate student Jeffry Grour.
3) UiO: Profs Torgeir Engeland, Morten Hjorth-Jensen and Eivind Osnes (UiO/CMA), PhD students Elise Bergli,
Maxim Kartamychev (UiO/CMA) and Gaute Hagen (UiB/CMA).
The project was started in the fall of 2003 to spring 2004, and we do expect several years of fruitful scientific
collaborations with an emphasis on the nuclear many-body problem and related topics. Our next plans will focus
especially on extending the coupled cluster methods to
a) include three-body forces, expected to be crucial for our understanding of shell closures,
b) coupling to weakly bound systems and inclusion of resonances and finally
c) extend these methods to studies of infinite matter. Maxim Kartamychev is involved with studies of three-body
forces, Gaute Hagen has worked on weakly bound systems, while Elise Bergli works on related many-body topics
for infinite matter.
We have recently performed the very first coupled cluster calculation of nuclear systems with valence particles. These
results are to be published in a forthcoming Physical Review Letters article. The ab initio coupled cluster theory
is a particularly promising candidate for studies of nuclei due to its enormous success in quantum chemistry. Our
two recent Physical Review Letters (one in press), describes an application of coupled cluster techniques to nuclear
structure. These techniques, which originated in nuclear structure theory, were thoroughly developed and exploited
in quantum chemistry for molecular electronic structure calculations. The paper describes an application of quantumchemistry inspired coupled cluster techniques for nuclear ground-state calculations and, for the first time, uses these
methods for the computation of excited states in nuclei. The coupled-cluster methods are very promising, since
they allow one to study ground- and excited-state properties of nuclei with dimensionalities beyond the capability
of present shell-model approaches, with a much smaller numerical effort when compared to the more traditional
shell-model methods aimed at similar accuracies. For the weakly bound nuclei to be produced by the proposed Rare
Isotope Accelerator it is almost imperative to increase the degrees of freedom under study in order to reproduce basic
properties of these systems. Judging by the success of coupled cluster theory in chemistry, it is expected that coupled
cluster methods will enable the ab initio microscopic calculations for nuclei up to the mass 100 region. Our codes have
now been extended so that we can deal with more than 800 active single-particle states.
A workshop on Advances in computational aspects in the nuclear many-body problem was held march 2004 at CMA.
David Dean (ORNL/CMA) and Morten Hjorth-Jensen (CMA) organized also a three month workshop at the Institute
of Nuclear Theory, University of Seattle, Washington, from september 27 till december 3. The other two co-organizers
were Bruce Barrett (UA, Arizona) and James Vary (Iowa State).
Large scale diagonalization techniques, with special emphasis on the nuclear many-body problem.
Here we have continued the development of our shell-model code for diagonalizations of large systems using the
Lanczos iteration scheme, of special mention is our recent parallel version of the shell-model code developed in Oslo.
Many of the applications are done in close collaboration with experimentalists and theorists in the USA and in Europe.
Dean, Engeland, Hjorth-Jensen, Kartamychev and Osnes published in 2004 a long review article in Progress of Particle
and Nuclear physics, see also the previous point. Maxim Kartamychev was employed in 2004 as a PhD student at the
Department of Physics and works on this project as well. His thesis project deals with the implementation of threebody interactions in our shell-model code and studies of such interactions for the coupled cluster method mentioned
above. He is associated with CMA.

Many-body perturbative approaches to weakly bound systems.
Due to the forthcoming large investments in the USA on the Rare Isotope facilities there is a strong need for
developing techniques for handling weakly bound systems. The last year, together with PhD student Gaute Hagen
from the University of Bergen and associated with CMA, we have developed tools for studying effective interactions
for weakly bound systems based on many-body perturbative approaches. These interactions will also be used in our
applications of the coupled cluster method discussed above. He defends his thesis april 2005 and begins as a post-doc
at Oak Ridge National Lab in june 2005.
Astrophysics
The physical description of the outer stellar atmospheres results in large sets of coupled partial differential equations. There
are major difficulties in constructing numerical methods for these equations related to highly nonlinear reaction terms and in
devising proper boundary conditions, an activity pursued at CMA. In addition, the activity in cosmology is focused on developing
improved algorithms for estimating correlation-functions of stochastic fields.
The dynamics of the outer Solar atmosphere is driven by the interaction of magnetic fields with convection in the outer
one third of the Sun. We have studied the diagnostics of these processes by performing detailed magnetoconvection
simulations. The results were presented at meetings and in a paper in Astrophysical Journal Letters, «Observational
Manifestations of Solar Magnetoconvection: Center-to-Limb Variation».
One of the major specific goals of the Physical Applications Project in the Research Plan is to «Complete a 3D
Radiation-Magneto-HydroDynamic code with non-restrictive boundary conditions». We have again expended
considerable effort in developing the 3D code during 2004.
While we concentrated attention on modeling of wave propagation in the Sun’s chromosphere in 2003, 2004 has seen
our efforts extend to the more realistic physical processes needed to model the Solar atmosphere, from convection
zone to corona, as a single dynamical unit. This requires that both radiative processes and thermal conduction be
included in the evolving models.
Another, time consuming, prerequisite is the construction of proper initial models of the Solar atmosphere on which
physical and numerical experiments may be performed. In June some of these models were presented at IAU’s
Symposium 223 in St Petersburg. Viggo Hansteen and post doc Boris Gudiksen are currently continuing this work in
an effort to understand aspects of coronal heating in the most common «Quiet Sun» atmosphere. In short, they are
searching for the magnetic field topologies and the magnetic field strengths conducive to achieving coronal heating
through magnetic reconnection such as appears to be occurring on the Sun.
On a related project a version of the 3D code has been utilized to study the expansion of the solar wind through
a magnetized corona. In Eirik Endeve’s PhD thesis «Helmet Streamers Gone Unstable» numerical studies of
the expanding corona, both open and closed, were made using a version of the 3D code described above. The
understanding gained from this thesis, as well as from our studies of the transport processes in plasmas described
below was in 2004 incorporated into a numerical study of the expulsion of the element Helium from the Sun in the
Solar Wind. This work, «Helium release from closed field regions of the Sun» has been accepted for publication by
the Astrophysical Journal. It was found that while it was possible to construct models in which significant amounts of
Helium are expelled as a result of magnetically closed regions opening, it is also true that the expelled Helium atoms
require quite some time to attain the temperatures necessary for acceleration; thus, we expect Helium enriched flow
to be preceded by a proton dominated precursor.
Finally, a new set of transport equations for fully ionized gases that was partially developed last year has been completed
and implemented in a numerical code by PhD students Marit Janse and Mari Anne Killie under the guidance of Egil Leer.
This has resulted in a paper, «Describing the flow of fully ionized, magnetized gases: Improved gyrotropic transport
equations», that has been accepted by the Journal of Plasma Physics.
15
In cosmology, the important results by Eriksen, Hansen, Banday, Gorski& Lilje (2004) showing an anisotropy between
hemispheres in theWilkinson Microwave Anisotropy Probe (WMAP) data that were reported inthe annual report
of 2003 have been supported by several studies andhave cought widespread interest. In a more detailed study of Npointcorrelation functions, Eriksen, Banday, Gorski & Lilje (2005, in press) have shown that the results are stable. These
results may hint towards a more complicated universe than we are used to thinking about, but the results need further
study from new experiments like Planck. Also, the results of Eriksen, Novikov, Lilje, Banday & Gorski (2004) that the
Minkowski functions of the WMAP first year data show significant non-gaussianities have been comfirmed by others.
Eriksen, Banday, Gorski & Lilje (2004) studied a method (called the ILC method) for foreground subtraction in CMB
maps that been used by the WMAP team and found that it easily could be very significantly improved by the use of
Lagrangian multipliers. This method is found to have strong limitations, but we also confirmed that several multipoles of
the WMAPmaps have a very peculiar behaviour.
The main reason for the future Planck satellite is to measure the power spectrum of fluctuations in the universe and
from them determining the cmain cosmological parametres. So far, all methods to acheive this for data of the size
Planck will give us (and even the size of the WMAP data set) have been forced to use approximations to the real
likelihood function for the data to estimate the power spectrum and the parametres. However, in collaboration with I.J.
O’Dwyer, J.B. Jewell, B.D. Wandelt, D.L. Larson, K.M. Gorski, S. Levin and A.J. Banday, we have implemented a method
using Gibbs sampling for the estimation. We have applied this method to the WMAP data and have shown that exact
estimation is indeeed feasible. Together with M. Chu and other collaborators, Eriksen has also improved these Gibbs
sampling methods by using the Blackwell-Rao estimator. Such modern statistical methods seem to be most useful in
astrophysical data analysis.

interest in essentially all aspects of computations, from computing and educational topics to the nuclear many-body
problem.
Workshop: Computational Finance and Physics
The workshop focused on computational methods and their analysis for problems arising in finance and physics.
Particular emphasis was put on the development and application of various types of Monte Carlo methods. The
speakers had background in physics, statistics, probability, finance, and partial differential equations, and the main
purpose of the workshop is to promote discussion across these disciplines.
16

Workshop: Camassa-Holm and other nonlinear dispersive equations
In recent years the so-called Camassa-Holm equation has caught a great deal of attention. It is a nonlinear dispersive
wave equation that models the propagation of unidirectional shallow water waves on a flat bottom. In another
interpretation it models finite length, small amplitude radial deformation waves in cylindrical compressible hyperelastic
rods. Also relatated is the so-called Hunter Saxton equation describing the director field of a nematic liquid crystal.
The Camassa-Holm equation possesses many remarkable properties. To mention a few, it has a bi-Hamiltonian
structure (an infinite number of conservation laws), is completely integrable, and has an infinite number of solitary wave
solutions, called peakons due to the discontinuity of their first derivatives at the wave peak, interacting like solitons. The
workshop focused on theoretical (existence, uniqueness, regularity, etc.) and numerical aspects of the Camassa-Holm
and other related nonlinear dispersive equations.
Miniworkshop: Mathematical Aspects of the Schroedinger Equation
The aim of this miniworkshop was to spark off a seminar series on mathematical aspects of various quantum mechanical
problems, spanning from time-dependent partial differential equations and few-body problems to methods for treating
many interacting particles. The seminar series starts was given in the fall semester (Computational Quantum Mechanics,
see below)
Internal seminar/workshop: Focusing the postdocs and PhDs of CMA
This two-day seminar focused on the research activity of the PhD-students and postdocs of CMA. The centre is fastgrowing, not least with respect to the number of fellows. This is a pleasant situation. We clearly demonstrate an active
and attractive research environment. However we see a clear demand for consolidating our activity, and to present
to ourselves some representative parts of it. What research is actually conducted at the CMA? The seminar then
presented a diversity of 16 representative presentations of the research activity conducted by CMA fellows. Socializing
17
and «teambuilding» were other aspects to the seminar, and these efforts are shortly presented under the Health,
Environment and Safety section
Workshop: Mathematical Finance and Copulas - 11th Workshop in Mathematics & Economics
Topics covered included
• Modelling dependence of multidimensional Lévy processes
• Optimal strategic allocation under estimation risk
• Endogenous regimes in the real term structure of interest rates
• Stock Return Predictability in a Production Economy
• Applications of Lévy copulas
• The Pyramid distribution, its copula and Lévy process
• Patient ownership
• Insurance and opportunities: the welfare analysis of wage inequality with flexible labor supply
Workshop: Multiscale modeling, and applications in fluid flow and material science
Despite the capabilities of modern multi-processor computers, it is currently not possible to model physical processes
with conventional numerical methods at the continuum scale and at the same time respect the constitutive laws at
e.g., the atomistic scale. A new type of multiscale mathematical methods have therefore emerged which attempt to
incorporate fine scale dynamics into the continuum models. These methods seek reduced computational complexity
compared with microstructure models, and offer new insight into the impact of fine scale features on the large scale
dynamics. Today, multiscale modeling and computation is one of the most active research areas in applied science. The
aim of this workshop was to discuss various approaches to mathematical modeling of physical multiscale phenomena
with weight on fluid flow and material science. The talks ranged from methodological developments to the use of
multiscale methods in specific real-world applications. An application of special interest to the organizers is porous
media flow, an area where we believe multiscale methods have reached a stage where they can be promoted to
the industry. The final day of the workshop was therefore devoted to multiscale methods in petroleum engineering.
The purpose was to create an arena where the Norwegian oil-industry can meet with representatives from the
international research community working on multiscale issues of relevance for the oil-industry.
Industry Day: Modeling and analysis of risk in electricity markets - recent research results
Trading electricity is a volatile business. The CMA Industry Day guided the participants through the highlights of recent
research on risk modeling and analysis of electricity markets, with a particular view towards the Nordpool market.
The focus was on specifying stochastic models for the spot and forward/futures price dynamics, how to estimate
these and techniques for pricing and hedging elctricity options. Through the day the participants learned advanced
analytical and numerical techniques, including the Heath-Jarrow-Morton (HJM) approach, Monte Carlo simulations, risk
measuring, currency risk, and copulas in multivariate modeling.
The CMA Industry Day also had an intended and clear public outreach profile, since we sought to create an arena
where recent academia research results could be adapted quickly by relevant market actors. See a separate description
on these aspects of the arrangement under a separate heading later in this report.
Workshop: Subdivision curves and surfaces
Subdivision curves and surfaces are a generalization of the well-known spline representation of curve and surface
models. They have been used extensively in computer graphics and have the potential to enhance current CAD
systems. The purpose of this workshop was both to introduce the basic mathematical concepts to a general audience
and to exchange ideas which could nurture future research collaboration. Topics covered include:
• Introduction to subdivision surfaces
• Local Corner Cutting
• Continuity analysis of univariate subdivision
• Shape analysis near extraordinary vertices
• Subdivision with transfinite boundary conditions
• Survey of Hermite interpolation using subdivision
• Hermite subdivision with shape constraints
• Factorization of spline subdivision matrices
• Approximation by subdivision curves: the role of parameterization
The CMA seminar Series 2004
This is the official seminar series of CMA It is intended for a rather broad audience with interests in mathematics and its
applications. The activity of the seminar aims at keeping a balance between theory, computation, and applications. The
seminar brings speakers from inside and outside of the centre, raising issues and exchanging ideas on topics of current
interest, mainly connected to the research plan of the CMA. A goal of the seminar is to foster working relationships
among mathematicians, computational mathematicians, and scientists from the applied fields and industry.
CMA Guest Lectures, 2004
This seminar at CMA is organized on a non-regular basis, and each speaker is announced here on the web page and
by e-mail. The seminar features speakers that are guests of the members of the centre. A presentation, which may be
specialized, is usually related to the research plan of CMA.
In addition to what has been mentioned above, ordinary weekly seminars and lecture series on selected topics have
taken place at the CMA, covering topics like:
• Large Deviation Theory
• Computational Quantum Mechanics
• Informal seminar on Geometry and PDEs
• Symplectic Geometry
• Weak Convergence Methods and Recent Mathematical Theory for the Compressible Navier-Stokes Equations
• Nonstandard Stochastic Analysis and Applications to Finance

The Board
Management philosophy
The board of CMA has for 2004 consisted of the following members:
• Kjell Bendiksen, chair, Managing Director of Institute of Energy Tecnology
• Suzanne Lacasse, co-chair, Managing Director of Norwegian Geotechnical Institute
• Trygve U. Helgaker, Professor at the Department of Chemistry, UiO
• Birger Kruse, Managing Director of the Faculty of Mathematics and Natural Sciences, UiO
• Svein Longva, Managing Director of Statistics Norway (until 2004), from 2005: State mediator of Norway
We firmly believe that novel research will arise as a result of a combination of a stimulating research environment,
focused research activities and academic freedom. The latter is important, but may potentially be problematic due to
the nature of the project, which has clear goals and a limited lifetime.
However, we have chosen an angle of attack which we feel covers all three perspectives. We believe that our strategy,
which we so far regard as successful, also contributes to increased research quality. In the Work environment survey
conducted in the fall semester (see separate section), the CMA members were very satisfied with the research
management of CMA. The strategy can be summarized as follows:
• All senior scientists at CMA have signed personal contracts in which they commit themselves to conduct research in
line with the research plan of CMA.
• We are focused when we produce descriptions of scientific positions for announcements, and in ranking of applicants.
We emphasize the interdisciplinary nature of CMA, both with respect to the different scientific fields, but also with
respect to the balance between theoretical, applied, and computational experience and interests of the applicants.
• We use our financial resources incentively, and we only grant research activities (seminars, workshops, guest
researchers, travelling) that are founded on our research plan.
The board reports to the Faculty management. It met twice in 2004, on March 16 and June 16. According to original
plans one more meeting was scheduled, in the autumn, but this was cancelled due to limited agenda items. For 2005
two meetings are planned.
Scientific Advisory Board
In this way we are filling our positions with candidates that have the right academic profile. The commitments of the
senior scientists and the daily research activities motivate all CMA members to pursue research in the direction of our
stated goals in the research plan.
A scientific advisory board was appointed late 2003 in accordance with original plans, and according to a right
specified in the general contract with The Research Council of Norway. So, CMA has chosen to distinguish between
the businesslike and the scientific content of the board activity. However, the board is still responsible overall for the
research plan, the advisory board is appointed by the board without any power to pass resolutions.
Daily leadership
The main subject for the advisory board will be to critically investigate and compare our research plan with our actual
work and progress, and to guide and suggest when changes or additions are implemented. They should know us, but at
the same time they should be courageous in challenging our scientific missions and disposals. Hence we need experts at
the forefront of international research activities within our fields, willing and capable of challenging us in this work.
CMA is on the daily basis run by the manager, Professor Ragnar Winther, the deputy manager, Professor Geir Ellingsrud,
and senior adviser and administrative leader Helge Galdal. These three constitute the leading group who have the
power of attorney to make running decisions on practical matters, financial transactions, research activities within the
frames of the budget and the research plan.
At the beginning of 2005 we have started the process of finding a new deputy manager, as Geir Ellingsrud will become
vice dean of the faculty from 2006. On the advice from the principal investigator group (see below) we have asked
Professor Fred Espen Benth to become the new deputy manager. He has accepted the «nomination». The CMA Board
approved the decition in the meeting on March 10, 2005. We expect that he will start his duties on July 1, 2005.
For more principal decisions and commitments, the leading group is extended to a group of principal investigators
consisting of 10 senior scientists of CMA. These are, in addition to the leading group: Tom Lyche, Ragni Piene, Tor
Dokken, Bernt Øksendal, Fred Espen Benth, Helge Holden, Morten Hjorth-Jenen, and Mats Carlsson. This group has
meetings when necessary, typically every second month. The group have a broad representation among the research
groups, and serve as a consensus and advisory council for the leading group, ensuring democratic and good decisions in
important choices of paths. Topics that are typically addressed in this group are:
•
•
•
•
•
20
The CMA-board aims at being a professional administrative board, emphasizing strategic and control functions, and
with clear instruction to handle budgets, accounts, and annual reports. Also the evolution of the research plan is a
major topic of the board. Helping the CMA leadership and the board to make wise decisions in that matter, a scientific
advisory board is constituted – see the next section.
Descriptions of scientific positions for announcement texts
Appointing evaluation committees
Final ranking of applicants for scientific positions
Budget disposals
Participation (or not) in boundary research actions wrt. the CMA research plan
The Scientific Advisory Board consists of:
• Professor Helmut Pottmann, chair (Vienna University of Technology, Austria),
• Professor Douglas N. Arnold (Institute of Mathematics and its Applications (IMA), University of Minnesota, USA),
• Professor Tom Bogdan (High Altitude Observatory, National Center for Atmospheric Research, Boulder, USA), and
• Professor Ivar Ekeland (University of British Columbia, Vancouver, Canada).
The group will play a crucial role when we revise the research plan in connection with the 2006 midterm evaluation
process.
Administrative Support
CMA has one administrative employee, senior adviser Helge Galdal. He is a member of the centre management, acting
as Ragnar Winther’s right hand, preparing general correspondence, reporting, board papers, budget and accounting
figures, financial transactions, communications, web-pages etc. Another role of his is to inspire and help the centre
researchers to write proposals for external funding. Finally he is responsible for coordinating all other administrative
functions which are «outsourced» as follows:
• The «first line services», meaning incoming telephones, faxes, mail, reception etc are provided by the secretaries of
The Department of Mathematics. They also cover CMA with accessories, minor equipment and so on, and CMA
uses the channels and customer relations of the department for more extensive purchases and consultancies.
21
• All financial transactions are authorized by Ragnar Winther and Helge Galdal in common. The resolutions are
executed by the secretary of economy at the Department of Mathematics, and he also provides help with budget
and accounting analysis, reports etc.
• IT-support is essential, and CMA again share the resources of our host department
• The Department of Mathematics has employed one person dedicated to deal with non-scientific matters for guest
researchers, exchange students and international doctoral or post doctoral fellows. She helps with housing, contact
with bureaucracy, kindergarten arrangements and so on.
• PhD-students must apply and be admitted to the official PhD-program of the Faculty of Mathematics and Natural
Sciences. During the three-year training period they regularly have to report on the progress. Upon dissertation
there are several needs, appointing and organizing the evaluation committee as well as executing the event itself. All
this requires administrative support, which are fully covered by the «closest» department in each case
(Mathematics, Informatics, Physics, or Astrophysics).
• In order to provide secure and efficient handling of personnel matters (contracts, payment routines etc), we are
totally dependent of the professional personnel administration provided by The Faculty administration. They have
dedicated one person who is responsible for all CMA-matters.
• CMA is also covered by the Faculty administration to ensure a secure archive system.
All together it is our experience that we have established an effective administrative organization, not least with respect
to cost issues. As far as possible we utilize the existing professional organization. CMA contributes to the surrounding
host units with financial support due to the extra load of work and services in the host organization. This system is
cost-effective (much cheaper than building a separate CMA-administration to cover the same services). We are also
confident that this system has helped CMA becoming an integrated part of a larger scientific community.
Revenues
Statement on the accounting and budgeting principles
The economy of CMA – meaning the financial plan, the cost plan, budgeting and accounting – has a complex structure
that is not fully covered in one complete electronic system. Not all figures are, or can be, included in the standard
UiO-routines. Even those which are parts of this system cannot necessarily be presented with respect to CMA as
one defined unit, since this would seriously disturb the figures of the involved departments. Hence a complete and
transparent system that presents the total CMA figures was a serious concern the first year, but we feel confident that
we have found good solutions that present the true and full picture. These solutions were conscientiously described in
the 2003 report, and need not be repeated. The same solutions and remarks apply this year.
Total revenue and expenditure figures
Below the main figures are presented. The elements in this presentation are based on the original financial and cost
plan of the CoE-contract. Hence we distinguish between the funding sources according to the guidelines of RCN.
Furthermore we present the expenditures as salary costs (meaning wages and costs thereof), indirect costs, teaching
services, equipment, and operational costs. More details, together with all notes, are presented in appendix 2 and 3.

Table 1. The main figures of revenues and expenditures, 2004 accounts and 2005 budget (x1000). The 1st and 4th columns
give the figures from the official RCN-contract on which the centre is established. Column 2 gives the figures from the adjusted
budget presented in the 2003 Annual Report. Column 3 and 5 are updated figures for this report.
* See the notes in appendix 3 of the Annual Report 2003 for this item. Last year we had a long-lasting job consolidating our
project portfolio, and even by the time of the first annual report this job was not fully surveyable. We now have a more precise
overview on the real connections and contributions these projects represent to the CMA research. Hence the item has vanished
into the different other items.
We are pleased to conclude that
• we during 2004 reached a revenue / expenditure balance (at least close to).
• the activity, in terms of costs, is at the budgeted and expected level.
• we have outperformed our estimates in the financial plan for 2004.
Changes in the cost plan
The total sum of expenditures indicates that we have managed to maintain the expected activity level in terms of the
cost plan, despite some obvious underestimates in some of the different items. The travelling and workshop activity
together with the guest frequency have been approximately as expected in 2004, although not at the cost level we had
in our budgets. However we regard it as a pleasant surprise that CMA personnel and incoming guests very often are
(partly) covered from other sources. In 2005 we will be even more active than in 2004 – even more workshops and
long term guests etc. Still we carefully downscale these budgeted expenses with respect to the 2004 figures.
22
23
We have also experienced that planned employments have had delayed starting dates, and that successful proposals
and applications gave income in 2004, whilst part of the activity will be conducted in 2005 (The Start pack of Professor
Kenneth Karlsen, and the educational reformation project «Computers in Science Education» are typical examples).
The most important resolution made in order to oppose the effects of such unexpected savings, has been to advance
the scheduled employment plan. We now engage more fellows by our own means than ever expected, even at full
scale. These resolutions will take full effect in 2005. We also further intensify the efforts on conferences, workshops,
incoming guests and outgoing travels. We will focus on even more long term research visits, and we are prepared to
invest in order to attract top profiles.
Hence we are comfortable with the presented budget for 2005.
SINTEF contributions: status, changes
Originally, the SINTEF personnel contribution was based on three persons from the Applied Geometry section,
Research Director Tor Dokken, Senior researcher Ewald Quak, and Senior researcher Michael Floater. However Floater
entered the full position at Dept of informatics in Nov. 2003 as stated above, and his specific SINTEF-contribution to
the CMA has not been replaced.
Despite this, we still see that the total SINTEF contributions have increased during 2004, both with respect to initial
level as well as the adjusted ambitions for 2004, presented in the 2003 Report.
The main reason is that more project activity of SINTEF is included in the CMA activity. Especially the project
«Graphics Hardware as a High-End Computational Resource» contributes significally, since two PhD-students are
included in the CMA-community. Also some of SINTEF’s collaborative activities like workshops take place at the CMA.
Changes in the financial plan
Recall that our budget philosophy is based on a really conservative strategy, meaning that we only state already
confirmed incomes, even though we are constantly working on new proposals and applications in order to strengthen
the conducted research at CMA. In this way the real impact of the specific effort each year is very transparent: The
difference between budgeted figures one year and the corresponding accounted figures one year later then represent
the annual additional results. For 2004 specifically, table 1 shows that we have raised MNOK 3, and certainly some of
these projects have deep impact also for the coming years. These incomes are of course included in the 2005 budget,
and we can conclude that we already have confirmed income that is MNOK 10 above the initial commitment made
in the contract negotiations with RCN when the centre was established. And that is for 2005 only. In the following
subsections we will comment on the most important new achievements.
UiO funding: Changes
The «Centre of Excellence» construction heavily rests on a solid contribution own funding from the host institution.
The main items are ordinary wages and indirect costs for all the senior scientists, and the centre contract commits the
host institution with a certain number of participating researchers and contributors. CMA has experienced that its host
actually goes beyond initial commitments. Some of these changes were commented upon in the 2003 Report, and will
not be repeated here. Since then, the following items represent the changes in the host contribution:
• One more full position (tenured) is allocated to the CMA-community (actually from November 2003). The
Department of informatics has employed Professor Michael Floater in a tenured position, and he is tied to CMA on
the same basis as all internal researchers of UiO.
• The Department of informatics also provided CMA with one additional 4-year PhD-position in 2004. Starting on
November 1, PhD-student Christian Schulz represents an increased host funding.
• Together the boards of the bachelor programmes «Physics, Astronomy, and Metheorology» and «Mathematics,
Informatics, and Technology», CMA applied for internal financial support in order to establish an educational reform
project «Computers in Science Education» (see separate chapter on «Basic Education» for more details). The
proposal was successful, and CMA has the project management and also hosts the project employee, Dr. Njål Foldnes.
• When Professor Kenneth Karlsen was employed in the new CMA-professorship from July 1, 2004, CMA applied for
a «start pack» on his behalf. The application was successful, and has brought CMA one two-year postdoc
position (Mostafa Bendamahne started on Nov. 1, 2004), and one three-year PhD-student (Imran Habib Biswas will
start on Apr. 15, 2005).
• Finally, several minor (internationalization) items add to the estimated budgets.
Project portfolio: status, development through 2004, outlook on the future
We reported last year that the creation of CMA led to a consolidation of existing projects in the nearby scientific
sphere. We boosted our estimated original figures. Both economically and by counting man-years this had a significant
impact on CMA. At the same time we shed some worries for the outlook on especially individual RCN-grants.
In 2004 these worries turned out to be relevant. Only one new PhD-student with an individual grant from RCN has
entered the CMA community in 2004, and she was already known to us one year ago as the last report was written
(and hence reported then).
However we have achieved success in other proposal and application processes, and several new fellows have entered
during 2004 or will be coming in 2005. The full list of projects is presented in appendix 4, but we will highlight two
achievements with considerable economic impact for CMA:
• Through EU’s FP6 we competed with success in the Marie Curie «Transfer of Knowledge»-scheme. Together with
«Centre for Nonlinear Studies (CENS)» in Estonia (appointed as an Estonian Centre of Excellence) we will run the
CENS-CMA project from May 1, 2005. The funding is up to € 850.000 over four years, divided approximately
equally on the two partners.
• Professor Kenneth Karlsen of CMA was successful in the YFF-call by the RCN. His project also had a considerable
own funding through his start pack from UiO, but the exclusive RCN-part is granted with MNOK 7 over 5
years, and started on Oct 1, 2004.
In addition, several other new activities have been granted or old ones prolongated with new funding. Among the
contributors are
•
•
•
•
FP6 Individual Marie Curie postdoc fellowship – Mikael Signahl two years from Feb.1 2005
Centre for Advanced Study, one postdoc fellow for one year (Aug 1, 2004 – Jul.31, 2005)
«Rogaland Forskning», one postdoc fellow for two years, starting in Feb. 15, 2005
The «Norwegian Participation in the Planck LFI instrument and cosmology with NOT»-project is prolongated with
two more years 2005-06, including one postdoc for two years
• The European Science Foundation has granted the AMaMeF-proposal with participation from 15 countries.
CMA-professor Brnt Øksendal will chair the project.
All together, we outplay our own figures and estimates for the total figures of 2004. However we only stated confirmed
activities in our last report, so the positive difference represents the net income raised during the last year.
Despite several successes in 2004 we are still concerned by the lack of possibilities in the RCN-system. We have
mentioned the individual grants, and we continue to be worried about this. Such projects seem to become more rare
24
25
in RCN. It seems as if there is a tendency towards larger and more compound programmes. We will compete on every
relevant area, and we hope to succeed. But we also have to be realistic. The centre activity itself is (and must be) the
dominating project activity of the senior scientists themselves. However, we have the capacity to do training activities,
which is why individual RCN-grants fit perfectly.
But also the expiring BeMatA-programme, which has served the mathematical communities in Norway with important
possibilities during the last few years, causes some concern. Together with all four mathematical university communities,
we last year submitted a proposal to the RCN, in which we argue for a new, broad mathematical research programme
in mathematics.
THE PEOPLE
Status and some statistics, employments 2004
On January 1, 2005, CMA consists of 77 people. They are all presented in appendix 1. In addition, appendix 1 contains
CMA members who completed their mission with CMA in 2004 (7), and also new employments with confirmed
starting dates early 2005 (4). Hence the presented lists include a total of 88 names (though if we restrict ourselves to
count heads, the final number is 85, since three persons appear twice, under different categories).
Only counting 2004-members (i.e. 88 - 4 =84) we may present the following statistical details on 2004-distributions:
We again strongly emphasize the importance of a success for this initiative. When this annual report is being written,
this proposal has been tied to the larger eVITA proposal, and is brought to a national hearing process. We somehow
feel that there is a chance that the methodology part, which we represent, will drown in the ocean of super computing
research – in a wide sense – that dominates the eVITA proposal. eVITA at least needs a kernel of methodology to avoid
fragmentation. The mathematics may constitute this glue.
Balance
• 19 senior scientists in full positions, 32 PhD-students, 20 postdocs, 8 adjunct positions, 2 in researcher positions,
1 scientific programmer, 1 project coordinator, and 1 administrative officer
• 71 men and 13 women
• 51 native Norwegians and 33 with foreign nationalities (representing 17 different countries)
• 35 employed by CMA, 30 by the host, 4 by SINTEF, and 33 through affiliated projects.
Man Year «production» 2004 and estimates for 2005
Due to starting efficiency, and not least a 6 months delay when entering our new premises, we accumulated a MNOK 4
surplus in 2003. The «Centre of Excellence»-scheme allows transfer of surplus, which was the natural resolution in last
year’s annual report. As a state official activity, we are not interested in accumulating further surplus, and as described
in the previous sections, we have now just finished our first full year, gained more experience on the cost level of
our activity, and we have geared the 2005-activity towards a moderate deficit. Further activity acceleration does not
seem plausible. Further employment commitments would cause too little space of action, or even a negative balance,
in the coming years. We have calculated (without argumentation in this report) the subsequent budget figures for the
following years, reaching a zero balance between estimated budgets and accounts at the end of 2006.
The careful reader will notice that the content of the latter bullet point above sums up to 102. This indicates that
several members are tied to CMA through different funding sources, either through parallel contributions (like the
SINTEF personnel), or through subsequent engagements (the host postpones affiliated projects, or CMA employs
former affiliates and so on). Appendix 1 provides the details. Table 3 below is calculated with respect to all these
details, providing the exact man year production figures of 2004 and new estimates for 2005. As in all budget
presentations, we use conservative figures; only confirmed new positions, and known contributions are taken into
consideration.
The following table shows estimated financial result of the CMA by the end of 2005.

As stated above, the CMA-community counted 77 «heads» on January 1, 2005. We also indicated that 4 new persons
with starting dates in 2005 are named in appendix 1 (specifically: postdoc Mikael Signahl starting on Feb 1, postdoc
Tore Halsne Flåtten starting on Feb 15, PhD-student Imran Habib Biswas starting on April 15, and postdoc Thilo
Meyer-Brandis starting on May 1). Furthermore, the budget of 2005 include 3 more postdoc fellows (starting May 1 x2
and July 1) and 1 PhD-student (starting July 1). These positions are all included in the table 3 estimates for 2005.
However, we have not estimated any other possible positions that we might receive through new projects or
agreements. Obviously several fellows, particularly among the PhD-students, finished or will finish their periods with
CMA during 2004/2005. Our efforts to address these challenges are described in another section.
Other contributors
As described in the Statements on the centre establishment, most of the daily administrative services are «outsourced».
We utilize the exisiting organization as optimal as we find possible. The following persons are most directly affected by
this system, and are specifically mentioned.
• Executive officer Dina Haraldsson and secretary Anita Smeby at the reception desk of Department of Mathematics
• Senior executive officer Diana Holand of Department of Mathematics, providing help with Norwegian beaucracy etc.
• Senior executive officer Jørg Gjestvang of Department of Mathematics is the book-keeper of CMA and also
provides service on reports and analysis.
• Computer engineers Terje Kvernes and Bård Kristiansen of Department of Mathematics who are responsible for
technical support
• Senior executive officer Grete Andresen of The Faculty of Mathematics and Natural Sciences is handling all
formalities wrt. personnel matters
Several other people could have been mentioned, in the four host departments, the faculty, and in the central
administration.
Guests
It is a privilege of ours to invite prominent guest researchers and –speakers as well as close collaborators of our group.
In 2004, we have received the following international long-term guests (by long-term we have defined more than 3
months):
•
•
•
•
•
•
Sep 1 - Jan 31 (05): Associate Professor Qiya Hu, The Chinese Academy of Science, Beijing, P. R. China
Aug 20 - Dec 31: PhD-student Anders Christian Hansen, Berkeley, USA
Aug 1 - Feb 15 (05): Associate Professor Francesca Biagini, University of Bologna, Italy
Apr 1 - Jul 1: Postdoc fellow Oleg Yablonski, Minsk, Belarussia
Apr 1 - Jul 1: Professor Zoran Popovic, University of Washington, USA
Mar 1 - Aug 31: Postdoc fellow Claudia La Chioma, HYKE postdoc, University of Rome, Italy.
In addition, we have welcomed 82 different international guests for periods of 1 day up to 3 months, some of them
twice or more. Appendix 6 contains the full list. Finally, we estimate that around 300 different national guests have been
received, many of them several times.
R E S E A R C H E D U C AT I O N
A main goal of CMA is the training of new rearchers. With now more than 40 PhD-students and postdocs among us
in our quite active research environment with several training activities, we believe that CMA has a significant chance
of being successful in this matter. However, as earlier stated, we are concerned about the possibilities of relevant
programmes and actions within the RCN system in the future.
In 2004, five members of CMA defended their doctoral theses, which is exactly the number that we estimated in last
year’s report. The five are:
• Njål Foldnes defended his thesis: «Polyhedra and Algorithms for some Knapsack Problems and Hop-constrained
Paths» for the dr. scient.-degree on March 31, 2004. He has been working under the supervision of Professor
Geir Dahl. Njål is, after short time, back with us at the CMA as the project coordinator of CMAs educational
project; «Computers in Science Education» – see separate description.
• Truls Flatberg defended his thesis: «Majorization and optimization related to graphs and (0,1)-matrices» for the
dr. scient.-degree on April 1, 2004. He has been working under the supervision of Professor Geir Dahl. Truls is now
employed in a researcher position at SINTEF.
• Trond Brenna defended his thesis «Data Reduction on Cubical and Spherical Domains Using High Dimensional Tensor
Splines» for the dr. scient.-degree on May 27, 2004. He has been working under the supervision of Professor Tom Lyche.
• Alberto Lanconelli defended his thesis: «White Noise Analysis and Stochastic Differential Equations» for the dr.
scient.-degree on September 16, 2004. He has been working under the supervision of Professor Bernt Øksendal.
Short after his defence he received a postdoc position at University of Lisbon, Portugal. Later in 2005 he will enter a
tenured position in Bari, Italy.
• Martin Reimers defended his thesis: «Topics in Mesh-based Modeling» for the dr. scient.-degree on September 24,
2004. He has been working under the supervision of Professor Knut Mørken. Already on October 1, Martin
entered a postdoc position at CMA.
Together with the three defences in 2003, eight doctoral candidates have so far successfully finished their PhDs at
CMA. In 2005, we expect that we will have another five new PhD defences in CMA. For comparison, our ambitions
were that 10 PhD-students should defend their work during the first five years of CMA, and 25 during all 10 years (see
the research plan).
Researcher school
On the request of the Ministry of Educational Affairs, «The Norwegian Council for Higher Education» has discussed
guidelines for a future system of «Researcher Schools» in Norway. The formal foundations for such a system still
seem unclear, but the University of Oslo has established a preliminary system, and in early 2004 they invited internal
applications. CMA was appointed, and hence is to be considered as a researcher school.
However the resources are very limited, CMA has received NOK 15.000 for 2004, and NOK 50.000 for 2005, and
these means do not make the big difference from our normal situation. We have though decided to arrange a national
intensive one-week researcher course in the fall semester. The topic will be PDEs and quantum mechanics, a central
and so far successful area for CMA itself, and also with many potential participants in other scientific communities,
especially within the nanotech physics / material science environments.
Finally, we regard the signalling effect as the most important feature of being identified as a formal researcher school.
We are visible on this arena, and in a good position if new efforts and resources are allocated to such a system.
Cotutelle agreements
Cotutelle (or joint) supervision and common PhD-degrees are important political signals in the educational Europe.
Many European institutions have established routines and some have also entered the first agreements. The University
of Oslo is not yet among these, but political emphasis has been put on this issue, and some frameworks are established
wrt formalities in agreements texts etc.
28
29
We are pleased to report that CMA will become pivotal in the University of Oslo, and probably in Norway at all. The
CMA associate Jon Mikkelsen Hjelmervik, who formally is employed at the SINTEF-driven Strategic Program «Graphics
hardware as a high-end computational resource», started his PhD-work on July 1, 2004. The GPU-activity is fully
included in the CMA-activity (CMA hosting the project’s second PhD-student Johan Simon Seland). Mr. Hjelmervik will
early 2005 enter a cotutelle agreement established between with University of Oslo/CMA and University of Grenoble.
In short, the agreement outlines the conditions on which he will alternate between the two institutions, supervisional
responsibility, formal titles and agreements upon the defence and so on.
B A S I C E D U C AT I O N
CMA is devoted to researcher education, and is not supposed to take major responsibilities at bachelor or master
level. Nevertheless, an entire period of study must consist of coherent parts. Moreover we are deeply interested
in candidates / applicants to our PhD positions with a solid and adequate background with respect to our needs
(and our conviction on how modern mathematics should be taught). This is partly why CMA has chosen to let the
senior scientists continue to teach at all levels, and not restrict ourselves to do PhD supervision and advanced level
teaching. Also our research plan signalizes this attitude. Based on the same philosophy, CMA has chosen to enter the
responsibility for the following project:
Bachelor level: Computers in Science Education
A fundamental prerequisite for good research in the CMA’s focused areas, is a supply of good candidates with a modern
education in mathematics and physics, supplemented with a firm basis in programming and computing. Traditionally,
programming and computing have been completely absent in the elementary syllabus of mathematics and physics. On
the other hand, research in a growing part of mathematics and physics makes heavy use of computations. We believe
that it is therefore time that the computational perspective is presented to the students in the mathematics and physics
courses even on the elementary level. Moreover, the CMA with its emphasis on computational science, has a special
responsibility to support the development of this kind of teaching.
CMA is contributing in this direction by hosting a project aimed at making the computational aspect of modern science
more visible in the University’s bachelor programs in the mathematically oriented sciences. The project coordinator
is Njål Foldnes, but Morten Hiorth-Jensen and Knut Mørken from CMA are also involved together with staff from
the Departments of Physics and Mathematics. The goal is to supplement the traditional undergraduate syllabus with
computer programming and numerical solution techniques from the very start. This is taught in two specialized courses
in the first term and will then be incorporated in the traditional mathematics and physics courses in later terms. In this
way, the students will be enabled to study realistic scientific problems right from the start of their studies.
The project was initiated in 2004, but makes extensive use of earlier uncoordinated work in the Departments of
Physics, Mathematics, and Informatics. A computational perspective is already present in the first year, but work is
currently focused on unifying this across the different courses throughout the relevant bachelor programs.
Master level:
We are aware that other Centres of Excellence have chosen to establish separate master studies. CMA has been firm
on the opposite solution; we rather want to influence on the existing programs by our ordinary and frequent teaching
duties. Also this leads us to be able to recruit from more than one specific program. This is obviously a more cost
effective strategy, and we may concentrate on our main objects in the researcher education. Of course, this strategy is
based on a confidence that the existing programs suit, and will continue to do so, our research profile. We do receive
qualified applications for our positions, both from international and national candidates.
30
We have though chosen two strategic actions with respect to master students:
• First, we have dedicated a reading room in our premises for master students, and this was completed in the summer
2004. From the fall semester, the room housed 12 master students. They are included in our mailing lists, they share
the kitchen and lunch area with us, and they are being invited to most of our scientific and social events.
• The second action is to move some central master courses to be taught in our seminar room.
Both actions are intended to bring the master students closer to us, and vice versa. We hope to build down artificial
borders so that the CMA appears as an obvious and attractive environment also among our nearest and maybe most
important recruiting base; UiO’s own master students with an interest for mathematics for applications.
C O O P E R AT I O N
Active Partner, SINTEF
SINTEF is CMA’s only active partner (i.e. contracted as a formal Centre of Excellence partner). We are pleased to
report that during 2004 there has been increasing cooperation in the daily work, and in terms of resources, we
outperform the estimates. In fact the estmates for 2005 shows a 200% increase compared with contracted commitment.
From CMAs point of view, we regard the cooperation so far as very constructive and fruitful, and most important: the
cooperation seems to imply really mutual benefits. We can list the main cooperative items in 2004 as follows:
• Tor Dokken and Ewald Quak continue to contribute as originally intended with the contracted 20% share in
addition to their 20% positions at CMA.
• SINTEF runs an RCN-initiated Strategic Institute Program «Graphics hardware as a high-end computational
resource», which is fully included in the CMA research activity. Two PhDs are associated to CMA, Johan Simon
Seland and Jon Mikkelsen Hjelmervik. Seland is intended to do his full PhD with us, and he sits permanently in our
premises. Hjelmervik will also become CMAs (and UiOs) first cotutelle student, see description in a separate section.
• We arranged two workshops in close and successful cooperation in 2004: The «Multiscale Modeling …» and «GPU
as a computational resource». Two new commonly arranged workshops are planned in 2005.
• CMA also benefits from other project activity of SINTEF. In 2004 this was especially applied to GAIA II and
[email protected] CMA members participate in different actions of these projects, research is conducted and results
obtained. In the appendices 6, 7, and 8 several items are connected to these projects.
• Finally, we would also like to mention that Dr. Ewald Quak has been very helpful with EU-proposals of ours. His
extensive experience with the EU-system is inestimable. He has advised and revised on a couple of occasions. With
his main effort, we explicitly succeeded with a proposal for a Transfer of Knowledge program towards an Estonian
Centre of Excellence. The CENS-CMA project will incept on May 1, 2005.
National cooperation
In the research plan of CMA, we state «As a national centre in applied mathematics our intention is to cooperate with
a variety of research groups in Norway which are in need of such expertise». The cooperation with SINTEF Applied
mathematics has proved to provide the centre with an open channel to industrial problems. If our capacity permits, the
centre may also be involved in other joint projects, for example in basic petroleum research or neuroscience.
The relation to SINTEF is outlined above. Another important goal was to hire some of the best researchers of other
institutions in Norway, who are closely related to our research. So we have done, and

Helge Holden, Norwegian University of Science and Technology,
Knut Aase, Norwegian School of Economy and Business Administration,
Xue-Cheng Tai, University of Bergen and CIPR (see below), and
Stein Arild Strømme, University of Bergen,
have all been employed by CMA in adjunct positions throughout 2004.
• The stochasticians also have a formalized cooperation with the University of Botswana. This cooperation involves
research and teaching, plus jointly organized biannual workshops in mathematical finance in the Southern African
region (since 1997). The next such workshop (number 5) will be held in Malawi in December 2005. For this we are
seeking support from IMU. Finally they will also participate in the IMU Millenium Science Initiative. Here the
University of Botswana and the University of Cameroon are two of the countries involved, where IMU wants
to establish mathematical research centers. In addition to the scientific activity by the stochastic analysis group, also
Professor Ragni Piene is involved in this cooperation at a high IMU administrative (and more general) level.
Together with another Centre of Excellence, Centre for Integrated Petroleum Research (CIPR), we entered a formal
agreement of cooperation in 2003. The intention is to cooperate on certain projects where the two centres have
complementary competence. One instrument is to use joint positions, and Runhild Klausen is now working in a twoyear postdoc position, one year paid by CMA, the next by CIPR. Her project within this CMA-CIPR alliance is related
to mathematical problems in reservoir simulation, in particular analysis of discretization methods which are well adopted
to reservoir problems.
As listed above, Professor Xue-Cheng Tai is also included by the agreement. He, however, was an intended member
of CMA in any case, from the proposal process and forward. But when both CIPR and CMA were appointed, this was
a very natural consequence. At CIPR Professor Tai is mostly responsible for the activity on inverse problems, while his
research towards CMA covers several central areas of partial differential equations such as finite element methods,
discrete solution algorithms, and level set methods.
In addition to the CIPR agreement, we late in 2004 entered the second national agreement, this time with Rogaland
Forskning in Stavanger. Postdoc fellow Tore Halsne Flåtten will in 2005-06 run his project «Pressure-based hybrid flux
splitting schemes for compressible flows» at CMA in collaboration with Professor Kenneth Karlsen of CMA.
Finally, during 2004, CMA has received more than 300 unique national guests for our events or for the purpose of
general research collaboration.
International collaboration
In our COE proposal, we named approximately 50 international collaborators, and they were only the very most
important ones. In 2004 we received 88 unique international guests (see appendix 6), of which 6 stayed with us
for more than 3 months. For comparison, we received 73 in 2003. 9 out of 11 research events had international
participation (and the last two were not intended to have) (Appendix 5a). CMA-members have been (co)organiser of
11 international conferences in addition to those at CMA (Appendix 5c). Among the 89 published papers in refereed
journals, 59 were written together with international partners (Appendix 7a). Out of 154 scientific talks outside CMA
(Appendix 8a and 8b), 139 were given abroad. CMA has a large circle of international collaborators and networking.
However, as a Centre of Excellence we also aim at establishing some formal and obliging institutional cooperation, and
we have taken a few steps towards this.
• We prepared an EU FP6 / Transfer of Knowledge proposal together with «Centre of Nonlinear Studies» a Centre of
Excellence in Estonia. The proposal was successful, and the project incepts on May 1, 2005, and will run for 4 years.
• Appendix 4 provides a full list of all projects at CMA, many of them with extensive international collaboration, and
also some of them coordinated by CMA / CMA-members.
• CMA, mainly through its stochastic analysis group, participates in the Mathematical Modelling program for Southern
Africa, based in Harare. Professor Bernt Øksendal is the Norwegian coordinator and Giulia Di Nunno and Knut
Aase are the other Norwegian members of the Steering Committee. This program is sponsored by NUFU and it
has been very successful: Since 1996 it has produced more than 50 Masters candidates and about 10 PhD students,
a substantial part of the whole production in the region. These are now all in important positions at Universities and
other institutions in the Southern African region. Currently 2 PhD-students are associated to CMA through this
project (Mataramvura and Kufakunesu, see appendix 1).

PUBLIC OUTREACH
CMA does not store chemicals or other possibly dangerous materials etc. No work-related accidents are reported in 2004.
It is important to make the general population more aware of the importance of mathematics in society, and CMA
intends to contribute. Norway has no tradition of great mathematical publicity, so any progression in this matter will not
just happen by itself. We have to seize all possibilities, and in 2004 we significantly increased the efforts and results:
Work Environment Survey 2004
The main effort on the HES-area in 2004 was a comprehensive work environment survey which was conducted in the
fall semester. The survey was anonymous, internet based, and led by the professional HES-section at the University.
The questions were adjusted according to local CMA-needs and -conditions in close cooperation with the CMAmanagement. The survey gave representative feedback, as 100% among the CMA employees answered (71% total).
The HES-section initiated the investigation with a goal for at least 50% response, which they regard as necessary. Full
report is available on reqest. The main results of the investigations may shortly be summarized as follows:
CMA members regard their work environment as good / very good. There are several positive «results»:
• Friendly, safe, supportive, stimulating, flexible environment
• Good management, flexible economy administration, satisfactory administrative and technical support functions.
Our main challenges are described as follows:
• Some uncertainties exist on who is formally responsible for their work at CMA (Department vs. Centre)
• More than 50% of PhDs and postdocs would prefer systematic appraisals (almost none among the senior staff
members…)
• Some dissatisfaction exist on
- Physical environment (ventilation and cleaning)
- Computer infrastructure and support
- Estetics and art
• We have registered 13 media appearances, among these both national radio NRK P1 and P2 as well as a feature
article in a main national newspaper «Dagbladet». The full list is presented in appendix 9
• Appendix 8c presents a list of talks, given in 2004 which were meant for a general audience.
• CMA has agreed with the organization www.matematikk.org to contribute as a five-year sponsor from 2003 -2007.
This organization aims at being a national net-resource for children, teachers, and parents, and was established in
the autumn 2001. During these years, they have constantly extended and improved their content, and in 2003 they
won the «Rosing Prize» for internet based information. They have thousands of users, and aims at being the top
national mathematics online resource for mathematics in the school. For CMA we regard this sponsorship as a safe
bet. Our contribution will reach much further here than if we established something similar on our own.
Finally we would like to give a few comments upon one of the scientific events; the CMA Industry Day on November 8
(scientifically described in the Scientific Activity Report – section). Here the main motivation was to establish an open
channel to recent research results for industry actors (specifically this year: for traders and analysts in the electricity
power market). 16 external participants registered, and by written evaluation we learned that we had hit the bull’s eye:
The participants had received valuable inputs for their daily work. We hope to establish this as an annual event.
The results were presented to us in December 2004, and the CMA management decided to initiate the following
immediate actions:
• Appraisals to be held in January/February 2005 with all PhDs and postdocs who are located in the premises of CMA.
• Strengthen the budget for IT-support
• Establish a wireless network for guests, plus generate easier routines for account allocations
• Estetics: Arts and some posters on the walls
• Health: Engage an ergonomist to suggest individual solutions on solvable problems
As this is being written (Feb05), most of these actions are already put into effect, but we will describe actions and
consequences more extensively in next year’s annual report.
Internal seminar and social events
On September 22-23, CMA arranged an internal seminar, focusing the research activity of the PhDs and postdocs.
55 members were able to participate, and we had 16 scientific presentations by our own fellows. The motivation
was clearly to consolidate a fast-growing activity. However, socializing and «teambuilding» were other aspects
to the seminar. The positive effects of a good dinner and a pleasant evening in nice surroundings should not be
underestimated. The feed-back from the participants were positive, and we regard the arrangement as successful, both
with respect to the scientific content as well as the social outcome.
We also arranged a common dinner in June, in addition to several smaller social events in the centre premises.

CMA-members
The following tables give a total overview of all CMA-members in 2004 and in the foreseeable future. Some positions
will be announced by CMA itself during 2005, but since no names are yet known, these are not included in the lists.
Any further speculations or not-yet-confirmed project fellows are also neglected (according to our budget philosophy
we do not calculate any new contributions). Any such contributions provided from now on, will appear in the 2005
annual report.
The information provides the foundations for the accounts and budget disposals in this report, and also for the statistics
on the personnel.

(Francesca Biagini, Aug 04 – Jan 05). In fact UiO provided further 62K (se note 26), but this item’s 25K were transferred
to our account. No similar contributions are yet confirmed for 2005.
11. Start Pack. UiO granted CMA a start pack, total contribution MNOK 1,8 over 3 years in connection with the
employment of Professor Kenneth Karlsen. With additional CMA-funding we chose to employ one postdoc (Mostafa
Bendamahne, Oct 04 – Sep 06) and one PhD-student (Imran Habib Biswas Apr 05 – Mar 08) in Professor Karlsen’s
research area.

appear in the financial plan in table 1 in the report. The content of this contribution is described in the report. So are
the deviations from earlier estimates. The contributions in this column are divided in two groups: the means placed to
our credit by specification, subjected to our resolutions (notes 7-12), and the representative funding, mainly in terms of
salaries, indirect costs, infrastructure (notes 18 and forward)

«Basic Education» in the report. We also intend to apply for further funding, but CMA has guaranteed the project
throughout 2005.
13. FORNY. CMA was granted NOK 100.000 from RCNs FORNY-program to run a survey in order to find possible
commercializable projects at CMA. The survey was completed, and has preliminary led to the Industry Day concept.

Notes on accounting 2004 and budget figures 2005
1. Total revenues and expenditures. The expenditure figures are the foundation for table 1 in this report. The
revenues, however, are here calculated regardless of the funding source (see notes 3,4,5,6 for details on the different
revenue items in table 1). All sums are obtained by adding the corresponding CMA Disposal figures with the
contributions from UiO, SINTEF and Other.

14. Projects refunded, first category. These three projects include fellows fully paid by CMA, but the real project
responsibility belongs to:
•
•
•
Centre of Integrated Petroleum Research (CIPR), Bergen (part of our established cooperation where CMA paid
one year for a postdoc fellow, Runhild Aae Klausen, CIPR the second), salary costs transferred to CMA for the
second year in order to avoid a new employment process)
Centre for Advanced Studies (CAS) has granted a one-year postdoc position for Steinar Børve, he remains
employed with CMA, but all salary costs are transferred to CMA
SINTEF runs the RCN project «Graphics Hardware as a High-End Computational Resource». One PhD-student,
Johan Simon Seland, is allocated full time to CMA, and a full PhD rate is transferred to CMA
15. Projects refunded, second category. For these projects, CMA does not have the employer’s duties, the centre
simply provides the working environment for
•
•
•
PhD-student Martin Groth (University of Vaxsjø, Sweden),
PhD-student Erik Christopher Dyken, postdoc fellows Tatiana and Vitaly Surazhsky (Department of Informatics,
UiO), and
Postdoc fellow Tore Halsne Flåtten (Rogaland Forskning)
For this service, and based on individual contracts, CMA invoices the project owners. The rest of the projects are
included under associated projects (hence included in notes 18,19, 23, 29)
16. Project An Ta Kieu. An individual RCN-grant (PhD-student An Ta Kieu), administrated by CMA
17. Div. income.
• 2004: 15 registration fees (of NOK 4000 each) for the CMA Industry Day, and NOK 10000 from Norsk Hydro for
the Multiscale workshop
• 2005 (Confirmed): NOK 59000 from CIPR Bergen and SINTEF for the multiscale workshop.
18. Salary costs for PhD students. This item is covering salaries and direct costs thereof for all our PhD-students in
2004, and those confirmed for 2005. The figures reflect the man year figures in table 3.
19. Salary costs for postdoc positions. As 18.
20. Salary costs for researcher positions. As 18. By «Researcher» we mean senior scientists (including the centre
manager), and adjunct positions.
21. Salary costs for guests. As 18. By «Guests» we have only counted official long term guests (who stay full time with
us for more than 3 months). They contribute to the CMA research simlilarly to CMA members, and we report their
results from the visiting period. Salary costs are estimated at an average level, comparative to ordinary CMA-members.
22. Salary costs for administrative and technical personell. As 18. Recall that a major part of the indirect costs (note
23) is dedicated to cover administrative and technical support for the centre as described in the section «Administrative
support». Hence this item covers senior advisor Helge Galdal and scientific programmer Andrew McMurry. For 2005
we have also included a 50% position from the summer to strengthen the IT support.
24. Additional areas. The amount appears in the original contract, and is specified to cover all areas beyond the offices
counted in 23, meaning other offices, laboratories, seminar-rooms, meeting-rooms, lunch area, other areas. CMA has
at its full disposal about 1400 square meters. In addition we have flexible solutions with our host if and when we need
additional space. We maintain the original figures for this part both for the 2004 account as well as for the adjusted
2005 budget.
25. Conferences. Workshops and conferences are main activities of the CMA. Appendix 5 contains a full list of the
2004 events. In 2005 we will arrange even more events.
26. Guests and travelling. This item reflects another main activity. Appendix 6 and 8 presents results of this extensive
bilateral activity. The specific UiO-contributions (NOK 62K) are internationalization means provided for EU / FP6
proposal preparations (travels to Estonia and Brussel in connection with the succesful CENS-CMA proposal)
27. Public outreach. This item covers publicity efforts, posters, design elements for web and brochures, reports (like
this) etc. We also plan to make efforts towards society in general, and children specifically. The support of www.
matematikk.org is included in this item.
28. Teaching services. CMA members are not exemted from teaching. On the contrary, we regard it as important
that we keep up with the teaching duties of the scientific community. However, in order to relieve us the most time
consuming parts of teaching, we have this specific budget item.
29. Various operational costs. This item is meant for the daily needs and actions that are not covered by any other
specific item. Rebuilding costs for our premises are included here. Also operational means for PhDs and postdocs are
included. For recruiting positions, common practice is to set aside some personal means for operational costs. In CMA
we calculate NOK 33.000 pr year for this purpose. All affiliates have the same sum available, and we have used the
same rate for the host-supported fellows.
30. Equipment. CMA itself mostly obtains computers and additional accessories. The centre members also make use of
existing equipment, especially the astrophysisists. In the original contracted budget we estimated this to a 2004 amount
of NOK 520.000 (2005: 531000). The activity goes on as expected, and we see no reasons to adjust this contribution
to the figures.
31. Annual Result. We conclude the accounting year of 2004 with a small surplus. With more experience we have
during 2004 geared the activity as high as we find reasonable, and these resolutions take full effect in 2005, in which are
signalizing that we will catch up with the transferred surplus from 2003.
32. Transfers. The CoE-scheme of RCN allows transfers, and to us this has been necessary to manage the financial
effects of the delayed entry in the premises in 2003. It has been an inevitable fact that we were totally dependent of
our own locations in order to increase the speed of activities. In addition we were a totally new constellation, and it
took time to employ a number of persons.
33. Accumulated result. These figures reflect the balance sheet in table 2, or vice versa.
23. Indirect costs, per individual. This item covers offices and infrastructure provided for each individual. We have
used prescribed rates at NOK 77.000 pr man-year except for PhD-students and Postdocs where we have used 95.000.
For UiO funded personell, SINTEF personell and affiliates, these figures appear equally as revenues and expenditures,
but we explicitly pay our host for all CMA employees, using the same rates.
