Hermann Flaschka

Hermann Flaschka ( born March 25, 1945 in Öblarn, Austria ) is an American theoretical physicist and mathematician.

Flaschka studied at the Georgia Institute of Technology (Bachelor 1967) and his PhD from the Massachusetts Institute of Technology Gilbert Strang ( Asymptotic Expansion and Hyperbolic Equations with Multiple Characteristics ). After that, he was a post-doc at Carnegie Mellon University, and from 1972 at the University of Arizona, where he was professor and since then remained. He has been a visiting professor at Clarkson University (1978 /79) at RIMS in Kyoto (1980 /81) and at the École Polytechnique Fédérale de Lausanne ( 2002).

Flaschka made ​​important contributions in the area of ​​exactly integrable dynamical systems, for example, he showed the exact solvability of the Toda chain (of Morikazu Toda ) and AC Newell, he led multi-phase solutions ( Multiphase similarity solutions) of nonlinear exactly integrable equations such as the Korteweg -de- Vries equation via differential equations, which are satisfied by their spectral parameters. Both were about even with the context of soliton equations to Lie algebras.

In 1980 he was co-founder of Physica D ( Nonlinear Phenomena ), which he publishes with. In 1995 he received the Norbert Wiener Prize. He is a Fellow of the American Mathematical Society.
