The existence of a fundamental solution of power growth for systems of difference equations
A. Ya. Belyankov Moscow Engineering Physics Institute
Abstract:
It is proved that any nondegenerate system of difference equations of finite order with constant coefficients has a fundamental solution, increasing not faster then some power of the distance from the origin. A proof is obtained by the reduction to a known similar result for the case of one equation.
