Richard S. Varga

Richard Steven Varga ( born October 9, 1928 in Cleveland, Ohio) is an American mathematician who deals with numerical analysis.

Vargas parents came from Hungary. He studied mathematics at the Case Institute of Technology ( bachelor's degree 1950) and Harvard University (AM 1951), where he received his doctorate at Joseph L. Walsh, 1958 ( Properties of a special set of Entire functions and Their repsective partial sums ). 1954 to 1960 he was involved in the Bettis Atomic Power Laboratory of Westinghouse in Pittsburgh in the development of nuclear reactors for the U.S. Navy. From 1960 he was a professor at Case Institute of Technology and in 1970 at Kent State University, where he was director from 1980 to 1988 and from 1988 to 2006 research director of the Institute for Numerical Mathematics.

Vargas has been dealing with numerical linear algebra and approximation theory. He has been a visiting professor at the Technical University of Munich (1974 ), the University of Karlsruhe (1988 ), the University of Hawaii, at Colorado State University, at Harvard (1963 ), the University of Texas at Austin, at universities in Chile, Saudi Arabia and Australia, and a visiting scientist at Caltech. In 1962 he was invited speaker at the International Congress of Mathematicians in Stockholm ( Higher order stable implicit methods for hyperbolic partial differential equations ). He is a Fellow of the American Mathematical Society.

He was in 1962 one of the first, the finite volume method introduced.

His doctoral Philippe Ciarlet heard.
