### The introduction seems poorly (i.e. confusingly) written to me, hopefully the rest of the book is better. Anyway, he says classical solutions of the wave equation $$ \frac{\partial^2}{\partial x^2}v - \frac{\partial^2}{\partial y^2}v = 0, $$ are twice continuously differentiable functions satisfying the equation everywhere.

In particular, is the measure if the roots of P(˘) are simple (L. Ehrenpreis, 1954). Representation (2) follows from the fact that equation (1) considered in Rn is equivalent to the equality 0.1. The main interest in the theory of partial differential equations has always been concentrated on elliptic and normally hyperbolic equations. During the last few years the theory of these equations has attained a very satisfactory form, at least where Dirich- let's and Cauchy's problems are concerned.
