The program includes tutorials as well as presentations on current research that are of academic and industrial interest. The school will also define collaborative research directions between mathematics and the geosciences in the quantification of uncertainty in geophysical imaging and inversion. The summer school is financially supported by the program for Collaborations in Mathematical Geosciences (CMG) of the National Science Foundation. Topics of the School Lectures on inverse problems, statistical inference, optimization, numerical modeling in geophysics, wave propagation, seismological imaging, and reservoir simulation. Presentations include current research in regularization of inverse problems, theory and applications of optimization, uncertainty analysis in seismological imaging, and physical constraints on inverse problems. A visit to the visualization center of the National Center of Atmospheric Research and a local geological field trip are part of the program. Target Audience The school will bring together graduate students, post-docs, and senior researchers in mathematics or the geosciences. For logistic reasons the number of participants is limited. About 40 students may receive financial support to attend the school. Speakers will be by invitation only. There will be an opportunity to present research through poster presentations.

Thus the random (Brownian) motion of cells or molecules is usually for computational purposes modelled by diffusion for example. There are many problems however where structure on the required length or time scale necessarily requires an eplicit description of some stochastic input. There are other problems where uncertainty in initial conditions for example leads to explicit use of stochastics in simulation. A further class of problems is those which are deterministic but extremely complex and simpler stochastic descriptions are sought. This one-day workshop is designed to bring together mathematicians working on Stochastic Differential Equations and applications scientists working in different fields and on different problems where computational modelling and understanding of relevant processes requires at least some stochastic aspect. Applications certainly arise in many areas - we are pleased to have speakers from weather/atmospheric modelling, hydrology and from the financial sector where stochastic descriptions are more prevalent - and we hope this workshop will enable cross-fertilisation of approaches and ideas both between applications and between theoreticians and practitioners. The workshop will take place at Oxford University Computing Laboratory, Wolfson Building, Parks Road, Oxford, starting at 10.00 am with coffee. Invited Speakers include: Roberto Buizza (ECMWF) Stochastic simulation of model uncertainty in probabilistic weather prediction Ian Cluckie (Bristol) Stochastic Hydrology and Uncertainty!? Ian Davies (University of Wales, Swansea) Stochastic heat and Burgers equations Allan Lane (Royal Bank of Scotland) The quest for better models when valuing Derivative Contracts in the Financial Markets Tony Shardlow (Manchester) Stochastic PDEs and spirals Andrew Stuart (Warwick) Homogenization for Inertial Particles. ------ Subject: PhD Research positions in Groningen From: Marco Martens Date: Fri, 05 Dec 2003 15:53:28 +0100 Dear Colleague, The dynamics group at the Rijksuniversiteit in Groningen, The Netherlands, has a few temporary Ph D research positions available. The specific areas are in low dimensional dynamic and some are related to applications of dynamics. Below you find the announcement for the position in "renormalization in Low dimensional dynamics". More information can be found at http://www.rug.nl/wiskunde/onderzoek/programmas/dynamicalSystems Please, forward this message to any student you think might be appropriate and interested in these positions. Thanks, Marco Martens ------ Subject: Faculty Positions at University of Florida From: William Hager Date: Sat, 6 Dec 2003 13:00:52 -0500 (EST) Funding is anticipated for two tenure track positions in Applied Mathematics. One position is targeted for Biomath while the other position is in any area of Applied Mathematics. APPLICATIONS MUST BE RECEIVED BY JANUARY 5. Send curriculum vita and list of publications to: Chair of Search Committee Department of Mathematics University of Florida Gainesville, FL 32611-8105 Applicants must arrange for three letters of recommendation to be sent directly to the above address. ------ Subject: Postdoctoral Position at University of Washington From: Bernard Deconinck Date: Mon, 1 Dec 2003 08:46:59 -0800 (PST) Postdoctoral fellowship in Applied Mathematics Hosting Institution: University of Washington, Seattle, WA Department: Applied Mathematics Applications are invited for a postdoctoral fellowship, to start September 16, 2004. Applicants are required to have earned a Ph.D. degree before the start date. The National Science Foundation has recently awarded a Focused Research Group (FRG) Grant to investigate nonlinear, three-dimensional waves in water of arbitrary depth to investigators at Seattle University (Mathematics, John Carter), the University of Washington (Applied Mathematics, Bernard Deconinck), Penn State University (Mathematics, Joe Hammack and Diane Henderson), Notre Dame University (Mathematics, David Nicholls), and the University of Colorado (Applied Mathematics, Harvey Segur). Researchers from McMaster University (Walter Craig) and the University of Toronto (Catherine Sulem) are also directly involved in this effort. More information on the grant and its participants is found at http://www.amath.washington.edu/~bernard/frg_surfacewaves.html. The Postdoctoral fellow will be based at the University of Washington, but can spend significant time at any of the institutions mentioned above. The fellow is expected to work on projects related to the FRG grant. These can include analytical and numerical work, as well as comparison with experimental data. Other duties include half-time teaching (two courses per year in the quarter system). This is initially a one-year position, with renewal for up to two additional years contingent on anticipated funding and on satisfactory performance in research and teaching. In addition to salary and benefits, the grant budget provides for equipment and travel reimbursement. Applicants should send a cover letter, AMS cover sheet, current CV, statement of research interest, and three letters of recommendation to Bernard Deconinck Department of Applied Mathematics University of Washington Campus Box 352420 Seattle, WA 98195 Please include an explicit statement allowing all PIs mentioned above to access and view the application materials. Review of Applications will begin on 1/19/04. Please e-mail questions to Bernard Deconinck at Bernard@amath.washington.edu. All institutions on the grant encourage applications from underrepresented groups in Applied Mathematics. Women, minorities, veterans and disabled persons are strongly encouraged to apply.
