$H$型群的次黎曼割迹

The Sub-Riemannian cut locus of $H$-type groups

Christian Autenried, Mauricio Godoy Molina

摘要:

本文证明了一类称为$H$ -型群的第二步幂零群的次黎曼割迹从原点出发对应于群的中心。我们得到这个结果完全描述的次黎曼测地线在组中,并使用这些来获得三个不相交的点集在组中的数量决定的测地线加入他们的起源。

英文摘要:

In the present paper we give a proof of the fact that the sub-Riemannian cut locus of a wide class of nilpotent groups of step two, called $H$-type groups, starting from the origin corresponds to the center of the group. We obtain this result by completely describing the sub-Riemannian geodesics in the group, and using these to obtain three disjoint sets of points in the group determined by the number of geodesics joining them to the origin.
