mathematician university professor
After studying physics at the University of Graz, he continued with his Doctor of Philosophy in theoretical physics.
He has authored more than 200 publications on mathematics and 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 1980-1981 and 1983-1984) and at the California Institute of Technology (Max Kade Scholarship 1987-1988) he was appointed at the University of Missouri where he is now Houchins Distinguished Professor.
In 2002 he was elected to the Royal Norwegian Society of Sciences and Letters.
In 2012 he became a fellow of the American Mathematical Society. Among his students is Gerald Teschl. with Barry Simon, The xi function, Acta with Rudi Weikard, Picard potentials and Hill’s equation on a torus, Acta with Rudi Weikard, A characterization of all elliptic algebro-geometric solutions of the AKNS hierarchy, Acta World War II General real potentials and the connection to the spectral measure, Annual of.
