摘要
讨论了食饵-捕食者模型中的中立型捕食者争抢食饵的时滞系统的Hopf分支,通过分析特征方程根的分布情况,得出系统正平衡点的稳定性及Hopf分支存在的条件.
A neutral predator - prey system with delay is investigated. The sufficient condition of the local stability of the posi- tive equilibrium point and the existence of Hopf bifurcation is obtained by discussed the roots of the characteristic equation.
