A semiclassical approximation of Feynman's path integral is derived which, in contradistinction to conventional formulae, remains finite in conjugate (focal) points and on caustics, exhibits the experimentally observed oscillatory behavior near these and reduces to familiar approximations far away.
The Abelian Higgs model is the simplest available, but it has to be considered in general R, gauges in order to avoid infrared divergences. A full derivation of the appropriate Nielsen identities in such gauges is given. Certain restrictions on the class of allowed R, gauges are found, which resolve
