Existence and Uniqueness of Periodic Solutions for a Class of Neutral Differential System

利用Krasnoselskii不动点理论,用分析的方法,获得了这一类微分系统周期解存在性与唯一性的充分条件.研究方法异于相关文献中常用的方法,获得的主要结论是新的.

using the analytical method and utilizing Krasnoselskii fixed point theory ,this paper qualitative and quantitative study the existence of periodic solutions for a class of neutral differential systems, and obtains some sufficient conditions of existence and uniqueness of periodic solution for this class systems. Our research method is different from the relevant literature,commonly used method, the main conclusions obtained are new, and promote the literature of the main conclusions.
