摘要
对具有Michaelis Mentln类型功能反应的非自治的 3种群捕食者 食饵系统 ,利用微分不等式方法以一些分析技巧 ,研究了这类系统的周期解问题 ,给出了正周期解存在的条件 .
The existence of positive periodic solution for a three-species predater-prey nonautonomous systems with Michaelis-Menten functional response is studied in this paper. By employing the differential inequality and some analytic techniques, the sufficient conditions for existence of positive periodic solution are presented.
