三维分段光滑动力系统的通有奇异性

Generic Singularities of 3D Piecewise Smooth Dynamical Systems

Otávio M. L. Gomide, Marco A. Teixeira

摘要:

本文的目的是提供一个讨论目前的研究方向,涉及典型的奇异性的三维非光滑向量场。一个简短的调查已知的结果。本文的主要目的是以最基本的形式描述褶皱-褶皱奇点的动力学特征,并给出其局部结构稳定性(或不稳定性)的完整而详细的证明。此外,折叠-折叠奇点的所有拓扑型的类都具有内在的特征。这种证明基本上遵循首先从一些线奠定了科伦坡,加西亚,杰弗里,特谢拉和其他人,其次提供了一个严格的数学处理下明确和清晰的假设和坚实的论点。应该强调的是,几何-拓扑方法使我们对T-奇点周围的动力学有了完全的数学理解。这种方法适用于一般分歧理论的应用。值得一提的是,在更高的维度上,对这一主题的理解仍然很少。

英文摘要:

The aim of this paper is to provide a discussion on current directions of research involving typical singularities of 3D nonsmooth vector fields. A brief survey of known results is presented. The main purpose of this work is to describe the dynamical features of a fold-fold singularity in its most basic form and to give a complete and detailed proof of its local structural stability (or instability). In addition, classes of all topological types of a fold-fold singularity are intrinsically characterized. Such proof essentially follows firstly from some lines laid out by Colombo, García, Jeffrey, Teixeira and others and secondly offers a rigorous mathematical treatment under clear and crisp assumptions and solid arguments. One should to highlight that the geometric-topological methods employed lead us to the completely mathematical understanding of the dynamics around a T-singularity. This approach lends itself to applications in generic bifurcation theory. It is worth to say that such subject is still poorly understood in higher dimension.
