John H. Walter

John Harris Walter (born December 14, 1927 in Los Angeles ) is an American mathematician.

Life

Walter studied at the California Institute of Technology with a bachelor's degree in 1951 and at the University of Michigan with a master's degree in 1953 and his doctorate in 1954 under Leonard Tornheim (Automorphisms of the Projective Unitary Groups) . He was then an instructor and assistant professor at the University of Washington and from 1961 Associate Professor at the University of Illinois at Urbana-Champaign , where he received a full professorship in 1966. In 1960/61 and 1965/66 he was visiting professor at the University of Chicago, 1967/68 at Harvard and 1972/73 at Cambridge.

He deals with the theory of finite groups and is known for Walter's theorem about finite groups with Abelian Sylow-2 subgroups from 1969 and Daniel Gorenstein and Walter's theorem about finite groups with dihedral groups as Sylow-2 subgroups. The Sylow theorems are mathematical theorems of group theory, a branch of algebra, and allow statements to be made about subgroups of finite groups and groups of finite order.

In 2012 Walter became a Fellow of the American Mathematical Society .
