一类Holling型动力系统极限环的全局分支

Global bifurcations of limit cycles in a Holling-type dynamical system

Valery A. Gaiko

摘要:

在本文中,我们完成了一个四次家庭的平面向量场对应的有理Holling型动力系统,模型的捕食者和他们的猎物在一个给定的生态或生物医学系统的种群动力学的全局定性分析。特别地,通过对全局分支的研究,我们证明了这样一个系统在一个奇点周围最多可以有两个极限环。

英文摘要:

In this paper, we complete the global qualitative analysis of a quartic family of planar vector fields corresponding to a rational Holling-type dynamical system which models the dynamics of the populations of predators and their prey in a given ecological or biomedical system. In particular, studying global bifurcations, we prove that such a system can have at most two limit cycles surrounding one singular point.
