Abstract: The predator-prey model with non-monotonic function is studied. The two growth rates are treated as corresponding bifurcation parameters, the bifurcation from a double eigenvalue is investigated by Liapunov-Schmidt procedure. The stability of these solutions is determined. Coexistence equilibrium can be reached between two species of prey and predator near trivial solution (0,0).
Key words: predator-prey model, bifurcation solution, consistently stability
摘要: 研究一类具有非单调功能函数的捕食-食饵模型,以物种的生长率作为分歧参数,利用Lyapunov-Schmidt约化过程,研究二重特征值处的分歧,并判定分歧解的渐近稳定性。说明捕食与被捕食的两种生物在平凡解[(0,0)]附近可以产生稳定的共存状态。
