Abstract
The general formalism for path integrals expressed in terms of an arbitrary continuous representation (generalized coherent states) is applied to give -number formulations for the canonical algebra and for the spin algebra, and is used to derive meaningful stationary-phase approximations for these two cases. Some clarification of a recent discussion by Jevicki and Papanicolaou for the spin case is given.
