The Cauchy Problem for Higher Order Equations,A function of n real variables u(x.,...,x.) is said to be analytic in a domain D if for some neighborhood of each point P = (ξ.,...,ξ.) in •D it is representable as a multiple power series in the x. − ξ., i = 1,...,n,..

The Cauchy Problem for Linear Hyperbolic Equations in General,We begin with the second order linear equation in two independent varia-bles.where the coefficients a,b,c,... are given functions of x and y in a domain D, having continuous second derivatives in D and satisfying the condition for being hyperbolic, ac − b. < O.
