## François Golse and Laure Saint-Raymond named recipients of SIAM’s premiering SIAG/APDE Prize

**July 20, 2006**

The SIAM Activity Group on Analysis of Partial Differential Equations (SIAG/APDE) Prize, established in 2005, is awarded to the author(s) of the most outstanding paper, as determined by the prize committee, on a topic in partial differential equations. The contributions must be contained in a paper or papers published in English in a peer-reviewed journal. This is the first year for the award.

François Golse and Laure Saint-Raymond were awarded the SIAG/APDE Prize at the SIAM (Society for Industrial and Applied Mathematics) Annual Meeting which was held in Boston from July 10–14, 2006. They received the SIAG/APDE Prize on behalf of their paper, "The Navier-Stokes Limit of the Boltzmann Equation for Bounded Collision Kernels," *Inventiones Mathematicae*, Volume 155, Number 1 2004, in recognition of making the definitive connection between weak solutions of the Boltzmann equation and Leray solutions of the incompressible Navier-Stokes equation.

François Golse received his Ph.D. in Mathematics from the Université Paris XIII in 1986, and joined the faculty. In 1987, he became a Centre National de la Recherche Scientifique (CNRS) research scientist at the École Normale Superieure. In 1993, he joined the faculty of the Université Paris VI. In 2006, he was elected Professor of Mathematics at the École Polytechnique in Paris.

Professor Golse is a member of the Institut Universitaire de France and has received several awards, including the Louis Armand Prize from the French Academy of Sciences and the Claude-Antoine Peccot Award from the College of France. His research has focused on the study of problems in mathematical physics, including the Boltzmann equation, the time dependent Hartree-Fock approximation, the distribution of free path lengths in the Lorentz gas, and the fluid dynamic limits of kinetic equations.

Laure Saint-Raymond received her Ph.D. in Applied Mathematics from the Université Paris VII in 2000. She joined the Centre National de la Recherche Scientifique (CNRS) as a research scientist in the Laboratoire d'Analyse Numérique, Université Paris VI. In 2002, she became a professor in the Laboratoire J.-L. Lions, Université Paris VI. She has received several awards, including the Louis Armand Prize from the French Academy of Sciences, the Claude-Antoine Peccot Award from the College of France, and the Pius XI Gold Medal from the Pontificia Academia Scientarium.

Professor Saint-Raymond's research has focused on the study of charged particles submitted to strong constant external magnetic fields, for example, in tokamaks and plasmas in planetary environments. From a purely mathematical perspective, her interests are in the kinetic theory of rarefied flows and the problems of singular perturbations. This work allows a rigorous multiscale analysis of the motion of plasmas. These results can be easily transposed to problems of rotating fluids subject to the Coriolis force.

The Society for Industrial and Applied Mathematics (SIAM) was founded in 1952 to support and encourage the important industrial role that applied mathematics and computational science play in advancing science and technology. Along with publishing top-rated journals, books, and *SIAM News*, SIAM holds about 12 conferences per year. There are also currently 45 SIAM Student Chapters and 15 SIAM Activity Groups.

SIAM's 2006 Annual Meeting themes included dynamical systems, industrial problems, mathematical biology, numerical analysis, orthogonal polynomials and partial differential equations.
