摘要

生物学中的数学建模在现实问题领域中是非常有趣的。本文主要研究两个猎物和一个捕食者之间的相互作用。在这里,我们的相互作用是基于两个猎物和一个捕食者之间的竞争,包括捕食者种群中的加性Allee效应以及Holling II型功能反应。进一步,这种直觉使我们能够证明模型的正不变性和有界性。这一分析表明,包括这三个种群共存在内,存在6个平衡点。还推导并证明了局部和全局的稳定性分析。本文还讨论了减少捕食者种群受Allee效应影响的种群的最优控制方法。数值模拟支持了我们的理论结果。

Dynamical Analysis of Two-Preys and One Predator Interaction Model with An Allee Effect on Predator
Mathematical modeling in biology is quite interesting in the field of real-world problems. This research paper focused on the interaction between two prey and one predator species. Here, our interaction is based upon the competition between two prey and one predator including an additive Allee effect in the predator population along with a Holling type II functional response. Further, this intuition allowed us to prove the positive invariance and boundedness of the model. This analysis shows that there are six equilibrium points including the coexistence of all three populations. Stability analyses are also derived and proved both locally and globally. Also in this paper, we discussed the optimal control approach to reduce the population affected by an Allee effect by the predator population. Numerical simulations are carried out to support our theoretical results.
