The Existence of Periodic Solutions for a Kind of Second Order Functional Differential Equations with Deviating Arguments

该文利用k-集压缩算子抽象连续性定理和一些分析技巧研究了一类具有偏差变元的二阶泛函微分方程周期解的存在性.该文的结果推广和改进了文献[1-2]的主要结果.

In this paper, by using the abstract continuation theorem of k-set contractive operator and some analysis techniques, the authors study the existence of periodic solutions for a kind of second order functional differential equations with deviating arguments. The results improve and extend the main results of the loaders [1-2].
