Speaker: Andras Vasy
Speaker Info: Stanford
Brief Description:
Special Note: Note unusual day
Abstract:

In this talk, partially on joint work with Jesse Gell-Redman, Nick Haber and Michal Wrochna, I will explain the properties of the Feynman propagator, i.e. the inverse of the wave operator on `Feynman function spaces', in various settings, concentrating on Lorentzian scattering metrics (a.k.a. asymptotically Minkowski-like spaces). I will also explain its positivity properties, and the connection to spectral and scattering theory in Riemannian settings.
