摘要
本文讨论一类具无穷时滞Logistic系统,得到了关于该系统的一致持久性结论,由此改进文[3]中概周期解存在定理,同时解决了该文中的一个猜想.
This paper discusses the Logistic equations with infinite delays. The anthor presents some results of persistence, and generalizes the existence theorems of almost periodic solutions obtained in [3]. Meanwhile, the open question proposed by G. Seifert[3] has been solved.
