一类具扩散的种群阶段结构模型的周期解

Periodic solution for the single-species Model with stage structures and diffusion

利用延拓定理讨论了一类具扩散的单种群阶段结构模型正周期解的存在性,其中,幼年和成年种群均具有扩散现象,得到了周期解存在的充分条件.

By using a continuation theorem based on Ganies and Mawhin＇s coincidence degree, the authors studied the global existence of positive periodic solution for a single species model with a stage structure and diffusion, where immature and mature species both have diffusion ability. Also, the sufficient conditions of the positive periodic solution were obtained.
