Title: Spectral asymptotics for stationary spacetimes
Abstract: We explain how to formulate and prove analogues of the standard theorems on spectral asymptotics on compact Riemannian manifolds -- Weyl's law and the Gutzwiller trace formula-- for stationary spacetimes. As a by-product we prove a semi-classical Weyl law for the Klein-Gordon equation where the mass is the inverse Planck constant.
