Existence of periodic solutions of a higher order difference system

Ronghui Hu and Lihong Huang

Abstract

By using critical point theorem, we study a higher order difference system, and obtain some new sufficient conditions ensuring the existence of periodic solutions for such a system.

Keywords: higher order difference system, periodic solution, critical point, link
