具有阶段结构的单种群模型概周期正解的存在唯一性及全局吸引性

Existence and Uniqueness and Global Attractivity of Positive Almost Periodic Solution of a Single-Species Model with Stage Structure

文章用一种新的方法研究了一类具有时滞的概周期单种群阶段结构模型,得到了模型存在唯一的正的概周期解,且此概周期解是全局吸引的.最后文章给出了数值模拟,支持了理论结果.

In this paper,a time-delay model of single species model with stage structure is considered by using a new approach.It is obtained that positive almost periodic solution exists and it is unique and global attractive.Numerical simulation results support the theory.
