We consider the Klein-Gordon equation on Minkowski space with a potential that decays suitably fast in spatial directions and approaches a limiting potential as t tends to infinity . The aim of this talk is to describe a global construction of the Feynman inverse for this problem. This is joint work with Moritz Doll and Jesse Gell-Redman (both at Melbourne).
