Description
We will review recent results on the propagation
of waves on domains, with emphasis on two extreme
cases: the exterior or the interior of a stricly convex
domain. Understanding the wave localization, its
amplitude and how it decays is fundamental for
several (unrelated) problems and we will describe an
interesting interplay between geometrical aspects and
degenerate oscillatory integrals that model waves
