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...
