Richard Steven Varga (/ˈvɑːrɡə/; born October 9, 1928) is an American mathematician who specializes in numerical analysis and linear algebra. He is currently an Emeritus University Professor of Mathematical Sciences at Kent State University and an adjunct Professor at Case Western Reserve University. Varga is known for his contributions to many areas of mathematics, including matrix analysis, complex analysis, approximation theory, and scientific computation. He is the author of the classic textbook Matrix Iterative Analysis. Varga has been the Editor-in-Chief of the journal Electronic Transactions on Numerical Analysis (ETNA).
Richard Varga was born in Cleveland, Ohio of Hungarian-born parents in 1928. He obtained a bachelor's degree in mathematics from Case Institute of Technology (present Case Western Reserve University) in 1950. Varga was a member of the collegiate wrestling team of Case.
Following the advice of Professor Max Morris at Case, Varga joined Harvard University for the master's degree and obtained an A.M. in mathematics. Continuing his doctoral work at Harvard under the supervision of Joseph L. Walsh, Varga worked on the theory of rational approximation of complex analytic functions. Varga received his Ph.D. degree in 1954 with a dissertation Properties of a Special Set of Entire Functions and their Respective Partial Sums.
