具有Allee效应和恐惧效应的Leslie-Gower捕食模型的分析

Analysis of a Leslie-Gower predator-prey model with Allee effect and fear effect

Lin Chen, Changrong Zhu

摘要:

本文研究了一类具有Allee效应和恐惧效应的Leslie-Gower捕食-食饵模型的动力学行为。首先,我们使用Blow-Up方法来探讨原点的稳定性。分析了系统非负平衡点的局部稳定性。以捕食者的增长率为Hopf分岔参数。并给出了模型发生Hopf分支的条件。用计算第一李雅普诺夫系数的方法讨论了弱中心附近的Hopf分岔方向。

英文摘要:

In this paper, the dynamical behaviors of a Leslie-Gower predator-prey model with Allee effect and fear effect are studied. First, we use Blow-Up method to explore the stability of the original point. Analyze the local stability of the non-negative equilibriums of the system. Taking the growth rate of predators as the Hopf bifurcation parameters. And give the condition of the model Hopf bifurcation. Using the method of calculating the first Lyapunov coefficient to discuss the direction of the Hopf bifurcation near the weak center.
