摘要: 讨论了具有Allee影响和病毒传播的捕食食饵模型在Neumann边界条件下正常数解的稳定性,给出了解的上下界,并利用能量方法给出了非常数正解不存在的条件,即在此条件下不会发生病毒感染。

关键词: Allee影响, 正平衡态, 稳定性

Abstract: The stability of the positive constant solution of the predator-prey model with Allee effect and epidemic transmission under Neumann boundary condition is discussed.Moreover,nonexistence condetions for non-constant positive solution are given.

Key words: Allee effect, positive steady-states, stability
