摘要 针对一类具有阶段结构的时滞捕食被捕食系统,通过讨论对应的超越特征方程根的分布,得到了存在小振幅周期解的充分条件,并推广了已有文献的相关结果. In this paper, a delayed predator-prey system with stage structure is investigated. Suttlcient conditions for the system to have small amplitude periodic solutions are obtained. The results here are development and generalization of the present results.
