摘要
Abstract
Existence of positive solutions of delay partial difference equations are studied.The positive solutions of the equations are given by using method of direct structure in the Banach space.The comparison theorems is established.Sufficient (sharp) conditions for existence of positive solutios of the equations are obtained.关键词
