摘要

我们研究了$ \mathbb{R}_+^2 $内部的离散Leslie捕食-捕食模型在不动点、分岔和控制下的局部稳定性分析。特别地,检验了对于所有参数,Leslie模型都具有边界平衡点和内部平衡点,并用平衡点处的线性稳定性理论研究了模型的局部稳定性。此外,模型在边界不动点处不发生翻转分岔,但在内部不动点处存在neimmark - sacker分岔,并且在该点处不存在其他分岔。此外,采用混合控制策略控制neimmark - sacker分岔。最后给出了数值模拟,验证了所得结果。

Discrete Leslie's model with bifurcations and control
We explored a local stability analysis at fixed points, bifurcations, and a control in a discrete Leslie's prey-predator model in the interior of $ \mathbb{R}_+^2 $. More specially, it is examined that for all parameters, Leslie's model has boundary and interior equilibria, and the local stability is studied by the linear stability theory at equilibrium. Additionally, the model does not undergo a flip bifurcation at the boundary fixed point, though a Neimark-Sacker bifurcation exists at the interior fixed point, and no other bifurcation exists at this point. Furthermore, the Neimark-Sacker bifurcation is controlled by a hybrid control strategy. Finally, numerical simulations that validate the obtained results are given.
