Abstract

In this paper, we study the existence of positive periodic solutions of the system of nonlinear neutral difference equations with variable delay $x(n+1)=A(n)x(n)$ $+\triangle g(n,x(n-\tau(n)))$ $+f(n,x(n-\tau(n))) .$ The main tool employed here is the Krasnoselskii’s hybrid fixed point theorem dealing with a sum of two mappings, one is a contraction and the other is completely continuous.
