本文研究了一类带有阶段结构和Ho1lingⅢ型滞后函数响应的捕食食饵模型的稳定性和Hopf分支的问题.利用微分动力系统的标准型和中心流形定理,获得了内平衡点局部稳定和周期解的方向性,推广了文献所得出的结论.
This paper investigate the stability and Hopf bifurcation of a delayed predator-prey model with Holling type-III response function and stage-structure for the predator.By applying the norm form of differential dynamic system and the center manifold theorem,we determined the stability of the interior equilibrium the direction of the period solution.Obviously,the result of Tian and Xu is promoted in this paper.
