Lebeau 2009

Lebeau studied from 1974 to 1978 at the École normal supérieure (Agrégation 1976), where he received his doctorate in 1978 (Thèse de troisième cycle) and 1983 (Thèse d'État) with Louis Boutet de Monvel . From 1978 he was at the CNRS as Attachée de Recherche. In 1985 he became professor at the University of Paris-Süd in Orsay (where he was dean of the mathematics faculty from 1990 to 1992 and was a member of the university council from 1994 to 1998), in 1997 at the École polytechnique and from 2001 at the University of Nice (Sophia-Antipolis ).

Lebeau deals with partial differential equations , the control of linear and nonlinear vibrations, and applications in mathematical physics. He solved a problem by Joseph B. Keller and Wassili Michailowitsch Babitsch (* 1930, V. Babich) about the semiclassical development in diffraction theory and proved that the problem of the Kelvin-Helmholtz instability in hydrodynamics is poorly posed (in the mathematical sense ).

Since 1997 he has been a corresponding and since 2005 full member of the Académie des Sciences , whose Prix Servant he received in 1992 and whose Prix ​​Ampère he received in 2003. From 1992 to 1997 he was a junior member and since 2003 he has been a senior member of the Institut de France. In 1992 he received the CNRS silver medal. In 1990 he was invited speaker at the International Congress of Mathematicians in Kyōto ( Interactions des singularités faibles pour les èquations d'ondes semi-lineaires ). In 1980 he received the Prix IBM France.

Nicolas Burq is one of his doctoral students .
