PREFAC E TO THE SECOND EDITION
The Handbook of Linear Partial Differential Equ ations for Engineers and Scien-
tists, a unique reference for scientists and engineers, contains nearly 4,000 linear partial
differential equations with solutions as well as analytical, symbolic, and numerical methods
for solving linear equations. First-, second-, third-, fourth-, and higher-order linear equa-
tions and systems of coupled equations are considered. Equations of parabolic, hyperbolic,
elliptic, mixed, and other types are discussed. A number of new linear equations, exact
solutions, transformations, and methods are described. Formulas for effective construction
of solutions are given. A number of specific examples where the methods described in
the book are ...
