三维分段光滑向量场中的一个渐近稳定的尖折奇异性

An asymptotically stable cusp-fold singularity in 3D piecewise smooth vector fields

Tiago De Carvalho, Marco A. Teixeira, Durval J. Tonon

摘要:

本文研究了由两个区域组成的$R^3$上分片光滑向量场的一个典型奇异性。在我们的研究对象,尖点-折叠奇点,我们考虑同时发生的尖点奇点的一个向量场和折叠奇点的另一个。我们展示了一个规范形式,提出了在分段光滑向量场搜索的最重要的属性之一:渐近稳定性。

英文摘要:

This paper is concerned with the analysis of a typical singularity of piecewise smooth vector fields on $R^3$ composed by two zones. In our object of study, the cusp-fold singularity, we consider the simultaneous occurrence of a cusp singularity for one vector field and a fold singularity for the other one. We exhibit a normal form that presents one of the most important property searched for in piecewise smooth vector fields: the asymptotical stability.
