摘要:本文研究了一个非自治的具有阶段结构和时滞的捕食–食饵模型.利用比较原理获得了系统持久性的条件,在假设系统为周期系统的条件下通过构造Liapunov函数证明了正周期解的存在唯一性和全局渐近稳定性.
A non-autonomous predator-prey model with digest delay and stage structure is considered in this article.The conditions of permanence of it are gotten by comparative principle.Furthermore,existence uniqueness and asymptotically stability of positive periodic solution have been proved under some assumptions if this model turns out to be a periodic system through constructing a Liapunov function.
