Boundary and Initial-Value Problems for Equations of Hyperbolic and Parabolic Type in Two Independent Variablesshed in their great variety. The simplest examples were mentioned in Sections I-2.3 and I-4.4. Among the methods for treating such problems, we mentioned the separation method, with which the reader will certainly be familiar in the case of simple problems, and the calculus of Laplace transforms, wh
