Jan Derezinski: Propagators on curved spacetimes Abstract: The Klein-Gordon equation has several natural Green's functions, often called propagators. The so-called Feynman propagator, used in quantum field theory, has a clear definition on static spacetimes. I will discuss, partly on a heuristic level, its possible generalizations to the non-static case. I will also describe a curious open problem about the self-adjointness of the Klein-Gordon operator. |
