Dan-Virgil Voiculescu

Dan - Virgil Voiculescu ( born June 14, 1949 in Bucharest ) is a Romanian- American mathematician.

Voiculescu studied from 1967 to 1972 at the University of Bucharest, where he earned his doctorate at Ciprian Foias 1977. From 1972 he was an assistant at the University of Bucharest in 1973 and until 1975 at the Institute of Mathematics of the Romanian Academy of Sciences. After the dissolution of the Institute in 1975, he was in Bucharest on INCREST. In 1986, he took advantage of a visit to the ICM in Berkeley to stay in the United States. At first he was a visiting professor in 1987 and professor at the University of California, Berkeley, where he was an associate professor in the spring of 1981 visiting. He has been a visiting professor at the Institut Henri Poincaré in Paris (2000 ), at the Centre de Recherches Mathematiques in Montreal (1991 ), at the University of Paris VI (1997 ) at the ETH Zurich (1997), at the University of Berkeley ( Miller Professor 1997/98) and a visiting scientist at the Fields Institute in Toronto, at the IHES, the Schrödinger Institute in Vienna and the Clay Mathematics Institute ( 2000).

In 2004 he received the NAS Award in Mathematics of the National Academy of Sciences for the development of the theory of open probability (Free Probability ) and specifically the application to random matrices and development of a new entropy concept and applications in the solution of difficult problems in the theory of Von Neumann algebras. The " Freedom " concept is a new concept within the non-commutative probability theory ( stochastic variables with non- commuting ) analogous to the usual statistical independence. Many phrases and concepts of ordinary probability theory there are analogies as a central limit theorem and a new entropy concept.

In 1997, he was a Guggenheim fellow. He was invited speaker at the ICM 1983 in Warsaw ( Hilbert space operators modulo normed ideals ) and gave a plenary lecture at the ICM 1994 in Zurich (Free Probability: random matrices and von Neumann Algebras ). He is a Fellow of the American Mathematical Society.

He has been married since 1979.
