[Video] Radiation fields for wave equations on asymptotically Minkowski spacetimes
Talk by Prof. Dr. Dean Baskin

Abstract: Radiation fields are rescaled limits of solutions of wave equations near "null infinity" and capture the radiation pattern seen by a distant observer. They are intimately connected with the Fourier and Radon transforms and with scattering theory. In this talk, I will define and discuss radiation fields in a few contexts, with an emphasis on spacetimes that look flat near infinity. The main result is a connection between the asymptotic behavior of the radiation field and a family of quantum objects on an associated asymptotically hyperbolic space. This talk is based on joint work with Andras Vasy and Jared Wunsch as well as with Jeremy Marzuola.
