具有阶段结构和周期投放的非自治单种群系统的周期解(英文)

Periodic Solution of a Nonautonomous Single Species Model with Stage Structure and Stocking

研究一类带周期投放的非自治阶段结构单种群模型 .利用泛函微分方程的单调和凹算子理论 ,得到系统存在一个全局吸引正周期解的充分条件 .

In this paper, we consider a nonautonomous singlepecies stage structured model with stocking. By using the theory of monotone and concave operators to functional differential equations, We establish conditions under which the system admits a positive periodic solution which attracts all positive solutions.
