FEYNMAN PROPAGATOR IN CURVED SPACE-TIME

Journal article

The Wick rotation is generalized in a covariant manner so as to apply to curved manifolds in a way that is independent of the analytic properties of the manifold. This enables us to show that various methods for defining a Feynman propagator to be found in the literature are equivalent where they are applicable. We are also able to discuss the relation between certain regularization methods that have been employed. © 1977 The American Physical Society.
