life and work

He studied from 1963 at the Johann Wolfgang Goethe University in Frankfurt am Main and received his doctorate there in 1968 under Friedrich Stummel and Harro Heuser ( existence and convergence of solutions to nonlinear elliptic difference equations and associated variation problems ). After an assistantship in Frankfurt and a year at the University of Rome , he completed his habilitation in 1970, then spent a year at the University of Pisa and held a substitute professorship in Heidelberg (1972/73) and a position as a visiting associate professor in Berkeley . In 1973 he became a professor at the University of Bonn . Until 2010 he was head of the department for applied analysis at the institute for applied mathematics.

Frehse's main research areas are elliptical and parabolic systems, calculus of variations and optimization. Among other things, he was the first to investigate higher order variation inequalities. He is the author of a textbook and over 120 publications. His co-authors include Josef Málek and Alain Bensoussan . At Frehse, 21 mathematicians did their doctorates (by 2009), including Michael Struwe and Hans Georg Bock .
