Paracausal deformations of Lorentzian metrics and Møller isomorphisms in algebraic quantum field theory
Abstract Given a pair of normally hyperbolic operators over (possibnly different) globally hyperbolic spacetimes on a given smooth manifold, the existence of a geometric isomorphism, called Møller operator , between the space of solutions is studied. This is achieved by exploiting a new equivalence relation in the space of globally …
