一类具有时滞的比率依赖捕食者-食饵模型的全局Hopf分支
GLOBAL HOPF BIFURCATION OF A RATIO-DEPENDENT PREDATOR-PREY MODEL WITH TIME DELAY

本文研究了一类比率依赖的捕食者-食饵模型的Hopf分支问题,运用吴建宏等人利用等变拓扑度理论建立起的一般泛函微分方程的全局分支理论,得到了由系统的正平衡点分支出来的周期解的全局存在性,最后利用数值模拟验证了理论分析的正确性.
This paper is concerned with a ratio-dependent predator-prey model with time delay. By using a global Hopf bifurcation result of general functional differential equations due to Wu Jianhong etc., the global existence results of periodic solutions bifurcating from Hopf bifurcations are established. Finally, numerical simulations are also included to support the theoretic analysis
