摘要
讨论一类时滞捕食-食饵模型,通过相应的特征方程及特征根的分布,分析滞量的影响,给出该模型的稳定性及Hopf分支存在条件.
In this paper,Hopf bifurcation of a predator-prey mode with time delay and harvesting is investigated.The effect of time delay is analysed by the cor responding characteristic equations.It is found that a Hopf bifurcation takes p lace when time delay passes a sequence of certain values.
