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

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

Vargas was particularly concerned with numerical linear algebra and approximation theory. Among other things, he was visiting professor at the Technical University of Munich (1974), the University of Karlsruhe (1988), the University of Hawaii , at the Colorado State University , in Harvard (1963), the University of Texas at Austin , at universities in Chile , Saudi -Arabia and Australia as well as visiting scholars at Caltech . In 1962 he gave a lecture 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 .

In 1962 he was one of the first to introduce finite volume methods .

Philippe Ciarlet is one of his PhD students .
