Publisher's Synopsis
Excerpt from Asymptotic Methods for the Solution of Dispersive Hyberbolic Equations
An important class of asymptotic methods is characterized by the fact that certain curves, often called rays, play a central role in the theory. The rays are of fundamental importance because all of the functions which make up the various terms of the expansion can be shown to satisfy ordinary differential equations along these curves. Thus, in a sense, the method is one which reduces partial differential equations to ordinary differential equations.
