Asymptotics of the radiation field on asymptotically Minkowski spaces

I will report on joint work with Andras Vasy and Jared Wunsch which determines the global asymptotic behavior of solutions of the wave equation on asymptotically Minkowski spaces. The rate of decay (and, indeed, all exponents in the asymptotic expansion at time-like infinity) is determined by the locations of the resonances of an associated operator on an asympotically hyperbolic space.Non UBCUnreviewedAuthor affiliation: Texas A&M UniversityFacult
