Hans Wilhelm Alt

Hans Wilhelm Alt (born 1945, Hilden) is a German mathematician, specializing in partial differential equations and their applications.

Alt received his Abitur in 1965 from the prestigious secondary school Helmholtz-Gymnasium Hilden.

In 1971 he received his PhD from the Georg-August-Universität Göttingen under Erhard Heinz with thesis Verzweigungspunkte von H-Flächen (Branching points of H-surfaces.)

[2] His research deals with, among other topics, free boundary value problems for elliptic partial differential equations and hyperbolic partial differential equations with applications to mechanics and thermodynamics.

For example, he has done research on axially symmetric jet flows and propagation of fluids in inhomogeneous porous media.
