Roger Temam

Roger Temam Meyer ( born May 19, 1940) is a French mathematician who deals with partial differential equations and their applications in continuum mechanics, especially the Navier -Stokes equations, and numerical simulation (Scientific Computing).

Temam earned his Agrégation 1962 and received his PhD in 1967 with Jacques -Louis Lions at the University of Paris. From 1960 he was an assistant in the Faculty of Mechanics, Faculté des Sciences de Paris. From 1967 until his retirement in 2003, he was the Maitre Conferences at the University of Paris-Sud. From 1972, he headed there as director the Laboratory for Numerical Analysis, 1977, the Laboratory of mathematics. At the same time he was also from 1986 temporarily at Indiana University as director of the Institute for Scientific Computing and Applied Mathematics, together with Ciprian Foias. 1968 to 1986 he was also the Maitre at the École polytechnique Conferences.

It dealt with the theory of dissipative nonlinear evolution equations such as the Navier -Stokes equations, in which he showed that the dimension of the attractors is finite (in many cases it could also barriers to specify them ) and in the theory he concept of inertial manifold introduced. He also dealt with the classical Euler equations for fluids and the Korteweg -de Vries equation. In geophysics, he dealt in the 1990s with climate models, especially the coupling of the atmosphere to the oceans. In plasma physics, he studied in the 1970s, the equilibrium shapes confined plasmas, partly in collaboration with the French tokamak group at the Nuclear Research Center in Fontenay -aux -Roses. Next he dealt with variational problems in the theory of plasticity.

Regardless of Alexandre Chorin 1968, he led the projection method for the numerical treatment of the Navier -Stokes equation.

1968 to 1984 he was scientific adviser to the INRIA, 1974-2000 at the CISIA.

In 1970 he received the Prix Peccot the Collège de France. In 2007 he became a member of the French Academy of Sciences, the Prix Carrière in 1977, the Prix Alexandre Joannides in 1993 and the Prix Jacques Louis Lions, he received in 2003. In 1989 he received the Seymour Cray Award for Scientific Computing. He became honorary professor of Fudan University in Shanghai in 1996. In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( Quelques methodes de en decomposition analysis numerique ). He is a Fellow of the American Mathematical Society.
