DESCRIPTION:Radiation fields are (appropriately rescaled) limits of soluti
 ons of wave equations along light rays.  In this talk I will describe a cl
 ass of (non-static) asymptotically Minkowski spacetimes for which the radi
 ation field is defined and describe the connection between the asymptotics
  of the radiation field and the resonances of a related Riemannian problem
  on an asymptotically hyperbolic manifold.  In particular\, even on Minkow
 ski space\, these methods give a new understanding of the Klainerman-Sobol
 ev estimates. This is joint work with Andras Vasy and Jared Wunsch.
