摘要
讨论了一类时滞差分方程正周期解的存在性,利用不动点定理,得到了正周期解存在的充分条件.
In this paper,the existence of positive periodic solutions for a class of delay difference equations is investigated, By using fixed point theorem, several sufficient conditions are obtained under which the existence of positive periodic solutions is guaranteed.
