摘要

. 本文主要研究具有加性Allee效应的离散时间捕食者-食饵系统的动力学问题。离散化是通过使用微分方程的分段常参数方法来完成的。首先,我们研究了平衡点的存在性和拓扑分类。然后研究了系统中周期加倍分岔和neimmark - sacker分岔的存在性和方向。此外,为了控制分岔引起的混沌,我们采用了混合控制技术。最后,对所有理论结果进行了数值验证

Stability, bifurcation, and chaos control of predator-prey system with additive Allee effect
. The current investigation focuses on the dynamics of a discrete-time predator-prey system with additive Allee effect. Discretization is accomplished by the use of a piecewise constant argument approach of differential equations. Firstly, we studied the existence and topological classification of equilibrium points. We then investigated existence and direction of period-doubling and Neimark-Sacker bifurcations in the system. Moreover, to control the chaos caused by bifurcation, we employ a hybrid control technique. Finally, all theoretical results are justified numerically
