The Feynman propagator is one of the main tools of Quantum Field Theory. I will review various definitions of this concept, including the operator-theoretic and out-in Feynman propagator. I will discuss various examples of spacetimes: stationary, asymptotically stationary, FLRW, deSitter and anti-deSitter.
I will consider both the stable and tachyonic case.
Based on joint work with Christian Gass.
