formulation of the path integral method is taken by another differential operator of the Dirac type.

The relevant properties of this operator are discussed. The semiclassical approximations are obtained by extending the results of catastrophe theory for the asymptotic evaluation of finite-dimensional integrals to the domain of path integration. Various forms of the uniform semiclassical approximations are obtained. Their validity and applicability are discussed. The method is illustrated by a solution of a simple example in which nongeneric catastrophe occurs.

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
