Fritz Gesztesy

Friedrich „Fritz“ Gesztesy (born 5 November 1953, Austria) is a well-known Austrian-American mathematical physicist and Professor of Mathematics at the University of Missouri, known for his important contributions in spectral theory, functional analysis, nonrelativistic quantum mechanics (particularly Schrödinger operators), and completely integrable systems (soliton equations). He has authored more than 200 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 (1977/82) and several stays abroad at the Bielefeld University (Alexander von Humboldt Scholarship 1980-81 and 1983–84) and at the California Institute of Technology (Max Kade Scholarship 1987-88) he was appointed at the University of Missouri where he is now Houchins Distinguished Professor.

In 1983 he got the 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.
