Periodic solutions for a coupled pair of delay difference equations

Advances in Difference Equations volume 2005, Article number: 218982 (2005) Cite this article

Abstract

Based on the fixed-point index theory for a Banach space, positive periodic solutions are found for a system of delay difference equations. By using such results, the existence of nontrivial periodic solutions for delay difference equations with positive and negative terms is also considered.
