XL.—The Linear Difference-differential Equation with Constant Coefficients

Published online by Cambridge University Press:  14 February 2012

E. M. Wright
Affiliation:
University of Aberdeen

Summary

Under the condition that one at least of the leading coefficients amn, a0n differs from zero, the equation

has as solution a series convergent for all x greater (or all x less) than a fixed number. The coefficients of the various terms in the series are expressed in terms of the arbitrary values of the solution and its first n derivatives in an initial interval of appropriate length.

This paper was assisted in publication by a grant from the Carnegie Trust for the Universities of Scotland.
