Klaus Bongartz

Klaus Bongartz (* 1949 in Koblenz ) is a German mathematician who deals with the representation theory of finite-dimensional algebras. Until 2014 he was a professor at the Bergische Universität Wuppertal .

life and work

Bongartz studied mathematics at the University of Mainz and the University of Bonn from 1968 to 1974 and then went to the University of Zurich as an assistant , where he received his doctorate in 1978 under Pierre Gabriel ( representations of the projective linear group in characteristic 2 ). In 1982 he completed his habilitation at the University of Zurich. From 1985 to 2014 he was a professor in Wuppertal.

In addition to the representation theory of algebras, he also dealt with tiling in discrete mathematics.
