摘要
研究一类具连续变量的时滞差分方程的周期解,利用krasnosel’skill不动点定理,获得了这类方程存在周期解的几个充分条件.
We study the periodic solution of delay difference equations with continuous variables. By using krasnosel'skill fired point theorem, several sufficient conditions for the existence of periodic solutions of the equations are obtained.
