摘要
利用Legett-Williams不动点定理对一类非线性泛函差分方程多个周期正解的存在性进行了讨论,得到该问题3个周期正解的充分条件.
The existence of multiple positive periodic solutions to nonlinear functional difference equation is considered by using the Leggett-Williams fixed point theorem, and three positive periodic solutions of this problem are obtained.
