摘要
考虑一类具有偏食习惯的捕食者与被捕食者模型。分析了该系统的奇点类型及稳定性。利用中心流形定理和Hopf分枝理论证明了该系统在一定条件下产生Hopf分枝,得到了中心流形的具体表达式。
A class of ecology models in predator-prey systems is considered. The qualitative Property and stability of the singular points of the system are analysed. Using Hopf bifurcation and Center manifold theorems, the bifurcation phenomena are discussed. Hopf bifurcation can occur in some valuse of parameters, The asymptotic formulas for the center manifold have been given.
