摘要
利用Krasnoselskii不动点定理讨论一类具分布时滞的退化微分系统的周期解存在性,给出了周期解的存在条件.
In this paper the existence of periodic solutions for a class of degenerate differential system with distributed delay was discussed using the Krasnoselskii theorem .Sufficient conditions of the existence of periodic solutions for the system were obtained .
