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

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

Malgrange is known, among other things, for the Malgrange-Ehrenpreis theorem on the existence of Greenscher functions of polynomial partial differential operators with constant coefficients. He also worked on the singularities of differentiable maps ( Malgrange's preparatory theorem ) and the algebraic theory of differential equations.

In 1988 he was admitted to the French Academy of Sciences , where he has been a corresponding member since 1977. In 1961 he received the Prix Carrière of the French Academy of Sciences. In 1978 he received an honorary doctorate from the University of Geneva . In 1966 he gave a plenary lecture at the International Congress of Mathematicians in Moscow (Théorie locale des fonctions differentiables). In 1985 he was President of the Société Mathématique de France .

Salah Baouendi is one of his doctoral students .
