Waves, Caustics and Thom's Theorem.
Abstract
The technique of Maslov for determining the first term in the asymptotic series solution of linear partial differential equation is extended to determine the full asymptotic series solution of the reduced Helmholtz equation for scalar waves propagated in an inhomogeneous medium. The algorithm requires the characterization of the medium by a canonical phase function determined from a criterion derived from Thom's classification of singularities. (Author)
