摘要:

利用Krasnoselskii不动点理论, 用分析的方法, 对一类中立型微分系统的周期解进行定性与定量地研究, 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.该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.

关键词: 中立型, 微分系统, 周期解, 存在性, 唯一性, 不动点理论

Abstract:

By using the analytical method and utilizing Krasnoselskii fixed point theory, this paper qualitatively and quantitatively studies 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 of systems. The research method is different from  the commonly used method. The main conclusions obtained are new, and promote the main conclusions in literature.

Key words: Neutral,  Differential system, Periodic solutions, Existence, Uniqueness, Fixed point theory
