Life

Jacques Dixmier began in 1942 his studies in mathematics at the École normale supérieure. He was hired in 1947 at the Centre national de la recherche scientifique, and there received his doctorate in 1949 at Gaston Julia; his dissertation was entitled Étude sur les variétés et les surgeon de Julia avec quelques applications. In 1949 he was at the instigation of Jean- Pierre Serre and Pierre Samuel member of the Bourbaki group in which he made ​​major contributions to the band via Lie algebras. After beginning his retirement Dixmier spent five years at the Institut des Hautes Études Scientifiques, he is Professor Emeritus at the University of Paris (Paris VI).

Dixmier worked mainly on operator algebras, in particular C *-algebras, and wrote a number of standard textbooks, which are also available in English translation. Frequently one finds the assertion came from him the name of von Neumann algebra for the initiated by John von Neumann operator algebras, but in his own words, this naming goes back to a proposal Jean Dieudonne.

Among his students Alain Connes, Nicole Berline and Michel Duflo.

In 1976 he received the Prix Ampere of the French Academy of Sciences, the 1992 Leroy P. Steele Prize of the American Mathematical Society, he was awarded the Émile Picard Medal of the Académie des sciences in 2001. In 1978 he was invited speaker at the International Congress of Mathematicians in Helsinki ( algebres enveloppantes ) and 1966 in Moscow ( dual Espace d'une ou d'un groupe algèbre localement compact).
