Roger Temam

from Wikipedia, the free encyclopedia

Roger Meyer Temam (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 acquired his Agrégation in 1962 and received his doctorate in 1967 with Jacques-Louis Lions at the University of Paris . From 1960 he was an assistant in the Faculty of Mechanics of the Faculté des sciences de Paris . From 1967 until his retirement in 2003 he was Maitre des Conferences at the University of Paris-South . From 1972 he headed the Laboratory for Numerical Analysis there as Director, and from 1977 the Laboratory for 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 . From 1968 to 1986 he was also Maitre des Conferences at the École polytechnique .

He 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 he could also specify bounds for them) and in the theory of which he used the concept of the inertial manifold introduced. He also dealt with the classical Euler equations for liquids and the Korteweg-de-Vries equation . In geophysics in the 1990s, he dealt with climate models, especially the coupling of the atmosphere to the oceans. In plasma physics , he investigated the equilibrium figures of enclosed plasmas in the 1970s, partly in collaboration with the French tokamak group at the nuclear research center in Fontenay-aux-Roses . He also dealt with problems of variation in plasticity theory .

Independently of Alexandre Chorin , he introduced the projection method for the numerical treatment of the Navier-Stokes equation in 1968.

From 1968 to 1984 he was a scientific advisor to INRIA and from 1974 to 2000 at CISIA.

In 1970 he received the Prix Peccot des Collège de France . In 2007 he became a member of the French Academy of Sciences , whose Prix Carrière he received in 1977, whose Prix Alexandre Joannidès in 1993 and whose Prix Jacques Louis Lions he received in 2003. In 1989 he received the Seymour Cray Prize for Scientific Computing. In 1996 he became an honorary professor at Fudan University in Shanghai . In 1970 he was invited speaker at the International Congress of Mathematicians in Nice (Quelques methodes de decomposition en analyze numerique). He is a Fellow of the American Mathematical Society and was elected to the American Academy of Arts and Sciences in 2015.
