Richard Steven Varga (October 9, 1928 - February 25, 2022)[1] was an American mathematician who specialized in numerical analysis and linear algebra. He was an Emeritus University Professor of Mathematical Sciences at Kent State University and an adjunct Professor at Case Western Reserve University. Varga was known for his contributions to many areas of mathematics, including matrix analysis, complex analysis, approximation theory, and scientific computation. He was the author of the classic textbook Matrix Iterative Analysis.[2] Varga served as the Editor-in-Chief of the journal Electronic Transactions on Numerical Analysis (ETNA).[3]

Birth and education

Richard Varga was born in

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

Partial Sums.[4]

While at Harvard, Varga also studied with

positive operators on partially ordered vector spaces
).

Career

From 1954 until 1960, Varga worked for

Padé approximation (often with Edward B. Saff, Jr.)—and analytic number theory, including high-precision calculations related to the Riemann hypothesis. He is also known for advocating experimentation in mathematics, and for writing a monograph surveying his contributions on scientific computing to resolve open problems and conjectures.[6]

Awards and honors

In 2012 he became a fellow of the American Mathematical Society.[7]
