Bernard Malgrange

Bernard Malgrange (* 1928 in Paris ) is a French mathematician who deals with differential equations.

Malgrange attended from 1947 to 1951, the École Normale Supérieure in 1955 and Laurent Schwartz at the University of Nancy doctorate ( Existence et approximation of the solutions of the équations aux dérivées partial et des équations de convolution ). During this time he was attaché de recherche of the CNRS. From 1955 he was Maître de conférences and then professor in Strasbourg. In 1960 he was Maître de conférences at the Faculté des Sciences in Paris and 1962 Professeur Titulaire. 1965 to 1969 he was a professor in Orsay. From 1969 he was a professor in Grenoble, from 1973 Directeur de Recherche at the CNRS in Grenoble at the Institut Fourier.

Malgrange is known among other things for the set of Malgrange - Ehrenpreis on the existence of green shear features of polynomial partial differential operators with constant coefficients. He also worked on the singularities of differentiable mappings ( preparation theorem of Malgrange ) and the algebraic theory of differential equations.

In 1988, he was inducted into the French Academy of Sciences, where he has been since 1977 a corresponding member. In 1961 he received the Prix Carrière of the French Academy of Sciences. 1978 Honorary Doctor of the University of Geneva. In 1966 he gave a plenary lecture at the International Congress of Mathematicians in Moscow ( Théorie des fonctions differentiables locale ).

His doctoral counts Salah Baouendi.
