Wave decay on asymptotically flat spacetimes

Peter Hintz (MIT)
Mathematics seminar
Mandag, 15 juni, 2020, at 16:00-17:00, Zoom (contact Jacob Schach Møller for details)

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 on $\mathbb R^3$; second, strengthening of Price's Law on Kerr spacetimes.

This talk is part of series of talks affiliated with the virtual Mittag-Leffler workshop "Scattering, microlocal analysis and renormalization", organized by Claudio Dappiaggi, Jacob Schach Møller and Michal Wrochna. The full schedule can be found at:
