Fritz Gesztesy


Friedrich "Fritz" Gesztesy is a well-known Austrian-American mathematical physicist and Professor of Mathematics at Baylor University, known for his important contributions in spectral theory, functional analysis, nonrelativistic quantum mechanics, ordinary and partial differential operators, and completely integrable systems. He has authored more than 270 publications on mathematics and physics.

Career

After studying physics at the University of Graz, he continued with his PhD in theoretical physics. The title of his dissertation 1976 with Heimo Latal and Ludwig Streit was Renormalization, Nelson's symmetry and energy densities in a field theory with quadratic interaction. After working at the Institut for Theoretical Physics of the University of Graz and several stays abroad at the Bielefeld University and at the California Institute of Technology he was appointed to Professor at the University of Missouri in 1988 and as Houchins Distinguished Professor in 2002. In 2016 he joined the faculty of Baylor University as Storm Professor of Mathematics.
In 1983 he got the Austrian Theodor Körner Award in Natural Sciences, in 1987 the Ludwig Boltzmann Prize of the Austrian Physical Society. In 2002 he was elected to the Royal Norwegian Society of Sciences and Letters. In 2013 he became a Fellow of the American Mathematical Society.
Among his students are Gerald Teschl, Karl Unterkofler, and Maxim Zinchenko.
