具有时滞和自食的阶段结构的合作系统的周期解的研究(英文)

The study of Periodic Solution a Nonautonomous Stage-Structured System With Time Delay and Cannibalism Two Kinds of Additive Maps on Operator Algebras

本文讨论一类具有时滞、阶段结构及自食的非自治合作系统的动力学行为,利用重合度理论中的的连续性定理,得到系统正周期解存在的充分条件。

In this paper,we consider a cooperative model,which has a discrete delay,stage structure and cannibalism.By using the continuation theorem of coincidence degree theory,a sufficient condition is obtained for the existence of a positive periodic solution of this system.
