Lax, Peter HS 3/ UZA 2 Fri, 22. Jan 10, 14:40
"Multiple characteristics of symmetric hyperbolic equations"
Abstract: I show that first order symmetric hyperbolic systems in three space and one time variable always have multiple characteristics if the order n of the system is congruent 2 mod 4, n = 2, 6, 10, etc. The proof has a topological flavour and leads to an interesting algebraic problem.

“ Analyticity of periodic traveling free surface water waves with vorticity ”
Abstract: Periodic irrotational traveling water waves are known to be smooth, with exception of the largest possible wave which has a corner at the wave crest (the lateral tangents being at an angle of 2\pi/3). Is the regularity of waves of small and moderate amplitude destroyed by vorticity? This is joint work with J. Escher.
