Abstract: The focus of this talk is the study of asymptotic expansions of linear waves propagating on stationary and asymptotically flat spacetimes. On the spectral side, I will describe a hands-on approach to resolvent expansions near zero energy based on recent work by Vasy. I will discuss two main applications: first, sharp decay for scattering by short range potentials in three dimensions. Second, a strengthening of Price’s Law on Kerr spacetimes.
