一类时滞Logistic方程周期正解的存在性

摘要

In this paper, we discuss the existence of positive periodic solutions for a Logistic equation with time delay by using the theory of coincidence degree. A new result is obtained. Some related results are improved.%我们利用重合度理论,讨论了一类时滞Logistic方程周期正解的存在性,获得了一个新结果,改进了某些相关的结果.
