【摘要】 考查了一类具时滞与捕获的捕食与被捕食模型,通过相应的特征方程,对时滞的影响做了分析,得出了当时滞经过一序列值的时候系统经历Hopf分支的结论。更多还原

【Abstract】 A predator-prey model with time delay and harvesting is studied in this paper.The effect of time delay is analysed by the corresponding characteristic equations.It is found that a Hopf bifurcation takes place when time delay passes a sequence of certain values.更多还原
