» Revised Research Plan

In 2008, CMA implemented its revised research plan after the midway evaluation. We reformulated our vision, now reading:To create significant development in modern mathematics based on interplay between theory, computations, and applications. Moreover we defined 12 specific focused areas for the remaining years. The full plan can be found on http://www.cma.uio.no/researchplan. We reported on significant progress in six out these twelve areas last year. This year we emphasize progress in the following nine:

Prizes and awards

As highlighted earlier, CMA’s Professor Bernt Øksendal received a prestigious “Advanced Grant” from the European Research Council, a branch of the EU commission’s FP 7. The award was project funding of 16 million NOK, and the project, entitled ”Innovations in Stochastic Analysis and Applications with emphasis on Stochastic Control and Information” (INNOSTOCH), started in September 2009. The ultimate goal is to cross the present research frontiers on a number of areas related to stochastic analysis and control theory.

CMA’s adjunct researcher, Professor Xue-Cheng Tai, who also holds a position at Nanyang Technological University in Singapore, was in November 2009 awarded the 8th Feng Kang Prize in Scientific computing, becoming one of only three scientists in the world to receive this prestigious award given by China this year. The Feng Kang Prize honors biennially Chinese scientists in China or abroad for significant contributions to scientific computing. Tai received this prize for his work on numerical analysis, especially his recent work on mathematical models for image processing and computer vision.

Dr David Dean, adjunct professor at CMA and senior scientist and director for strategic planning at Oak Ridge National Laboratory, has been offered and has accepted a position in President Obama’s administration. He took up a position as Senior Advisor to the Under Secretary for Science, Dr. Steven Koonin, at the U.S. Department of Energy in Washington DC. The cabinet ministry is headed by Secretary Steven Chu, Nobel Laureate in Physics 1997.

Main conclusions and remarks

The accounts show a continuous growth in activity. However, the main reason for the increased revenues and corresponding carry- over is the pre-financing of Professor Bernt Øksendal’s ERC Advanced Grant at 5,7 millions. In fact we have, in accordance with our ambitions from last year’s report, reduced the fiscal carry-over from our basic CMA-activity to close to zero (KNOK 88 – see appendix 2 for details). The remaining KNOK 7568 are tied to future obligations within the project portfolio.

CMA’s financial situation still provides a solid foundation for stable and flexible project management and long term research, which in turn make us able to run a healthy and highly competent centre.

NB! The accounts show total revenues at MNOK 64,6, but in the brief summary on page 2 we present 63,6. The difference is due to ABoverhead revenuesC from own projects (Note 1). DEF 14 GHI CENTRE OF MATHEMATICS FOR APPLICATIONS – ANNUAL REPORT 2009 CMA 2009

On Dec 31, 2009, CMA counted 95 people. In addition 16 completed their time with CMA during the year. They are all presented in appendix 1, together with those who are confirmed incoming in early 2010 (4). We present the following statistical details on the 111 members of 2009: • 23 senior scientists, 43 PhD-students, 25 postdocs, 14 adjunct researchers, 6 other • 89 men and 22 women (19,8%) • 58 native Norwegians and 53 (47,7%) of foreign nationalities from 24 different countries • 46 funded/employed by CMA, 32 by the host, 12 by SINTEF, and 31 through affiliated projects.

Table 2. Calculation of person-years in CMA, taking the funding source into account

Clearly 2009 has brought the highest level of activity so far in terms of person-years. As we enter 2010, it is natural to foresee a modest down-scale. The CoE funding will last three more years, and we will soon pass the line where new PhD-employments will exceed the lifetime of the centre. According to our long term plans, 2010 will require reducing the basic CoE-activity. However our efforts on the project portfolio will hopefully also bring new researchers and activity to the centre.

We are deeply interested in candidates / mathematics and science. A challenge is that we receive applicants to our PhD positions with a solid and adequate students from other institutions that lack this perspective background with respect to our needs (and our conviction on and therefore find some of our advanced courses difficult. It is how modern mathematics should be taught). This is partly why therefore essential that the ideas within the CSE project can CMA has chosen to let the senior scientists continue to teach be spread to other institutions from which we recruit students. at all levels, and not restrict ourselves to do PhD supervision This is starting to happen, and the Norwegian University of and advanced level teaching. Also our research plan signalizes Science and Technology in Trondheim is now working actively this attitude. Based on the same philosophy, CMA has chosen on CSE-like ideas. to enter the responsibility for the CSE project, see below: A major event in 2009 was a presentation of the CSE project for Moreover, rather than establishing separate master programs, the Minister of Research and Higher Education, Tora Aasland, CMA wants to influence on the existing programs by our with her key staff, as well as the new Rector, Ole Petter Ottersen, ordinary and frequent teaching duties.

First, 53 of CMA’s 111 members in 2009 were non- Norwegians, representing 24 different countries. We always receive many international applicants when announcing Active Partner, SINTEF positions. Moreover, in 2009 we received 293 international guests from 39 different countries (all listed in appendix 6). SINTEF is CMA’s only active partner (i.e. contracted as a formal Centre of Excellence partner). In each annual report, we have All 8 internally arranged conferences/workshops had reported an increased cooperation. In 2009, there were no international participation (Appendix 5a). CMA-members have new projects in addition to those reported last year, but the been (co)organiser of 27 international conferences in addition activities within the established projects have increased. As to those at CMA (Appendix 5c).
