一类三维Lotka-Volterra系统的全局动力学

Global dynamics of a family of 3D Lotka-Volterra Systems

Adrian C. Murza, Antonio E. Teruel

摘要:

本文分析了一类三维Lotka-Volterra系统在不变有界区域上的流。这个区域内部的流动行为很简单:要么每个轨道都是周期轨道,要么它们从一个边界移动到另一个边界。然而,在边界的极限集的完整的研究允许理解的分歧发生在该地区作为一个全球性的分歧,我们表示为焦点-中心-焦点分歧。

英文摘要:

In this paper we analyze the flow of a family of three dimensional Lotka-Volterra systems restricted to an invariant and bounded region. The behaviour of the flow in the interior of this region is simple: either every orbit is a periodic orbit or they move from one boundary to another. Nevertheless the complete study of the limit sets in the boundary allows to understand the bifurcations which take place in the region as a global bifurcation that we denote by focus--center--focus bifurcation.
