Counter-examples to the Strichartz estimates for the wave equation in domains II

Analysis of PDEs 2010-02-08 v3

Abstract

We consider a smooth and bounded domain of dimension d>1 and we construct solutions to the wave equation with Dirichlet boundary conditions which contradict the Strichartz estimates of the free space, at least for a subset of the usual range of indices. This is due to micro-local phenomena such as caustics generated in arbitrarily small time near the boundary.
