Title: Asymptotics for the wave equation on black hole spacetimes
Abstract: We will present the precise late-time asymptotics for scalar fields on both extremal and sub-extremal black holes including the full Reissner-Nordstrom family and the subextremal Kerr family. Asymptotics for higher angular modes will be presented for all cases. Applications in observational signatures will also be discussed. This work is joint with Y. Angelopoulos (Caltech) and D. Gajic (Cambridge)
Bio: Stefanos Aretakis completed his PhD at the University of Cambridge and is currently an Assistant Professor in the Department of Mathematics at the University of Toronto St. George and in the Department of Computer and Mathematical Sciences at the University of Toronto Scarborough. He is interested in problems concerning the mathematical analysis of differential equations in general relativity with focus on the stability problem for black holes.
