Ciprian Foias

Ciprian Ilie Foias ( born July 20, 1933, Resita, Romania ) is a Romanian- American mathematician.

Life

Foias his doctorate in 1962 at the Institute of Mathematics of the Romanian Academy of Sciences in Bucharest in Miron Nicolescu and his Habilitation ( Ph.D. according to an Eastern European tradition ) in 1968 at the University of Bucharest, where he was professor from 1966. From 1979 he was professor at the University of Paris-Sud in Orsay (until 1983 ) and at the same time at Indiana University, where he is a professor since 1983 Distinguished. Today he is a professor emeritus.

Foias dealt with the theory of operators in Hilbert spaces, application of methods of the theory of dynamical systems of partial differential equations ( and study of the Navier -Stokes equations), interpolation theory, Toeplitz operators. He practiced and applied research, such as signal processing in geophysics, control theory, economics, statistical theory of turbulence, estimating the dimension of attractors in hydrodynamics.

In 1995 he received the Norbert Wiener Prize. He is a Fellow of the American Association for the Advancement of Science ( 1987) and honorary member of the Hungarian Academy of Sciences (1993) and of the Romanian Academy of Sciences ( 1994). In 1998 he was Ulam Scholar at Los Alamos National Laboratory. 2000 Honorary Doctor of the University of Amsterdam and received the first - Szőkefalvi Béla Nagy medal. In 1978 he was invited speaker at the International Congress of Mathematicians in Helsinki ( contractive inertwining dilations and waves in layered media) and in 1970 in Nice ( Some applications of structural models for operators on Hilbert space).

His doctoral include Dan Voiculescu and Adrian Ocneanu.
