Following a review of standard semiclassical approximations to wave equations in the configuration-space formulation, an approach based on a coherent-state representation is fully developed. Unlike direct configuration-space approaches, it is shown that the coherent-state formulation leads to a global, uniform, semiclassical configuration-space approximation, which has distinct advantages when one is faced with numerous caustics.
