左不变Finsler度量的齐次测地线

Homogeneous geodesics of left invariant Finsler metrics

Dariush Latifi

摘要:

本文研究了李群上左不变Finsler度量的齐次测地线集。我们首先给出一个简单的标准,特点测地线向量。作为应用,我们研究了李群上双不变Finsler度量的一些几何性质.特别地,给出了左不变Randers度量是Berwald型的一个充要条件.最后给出了齐次测地线与限制Finsler度量的临界点的对应关系。从而得到了关于齐次测地线存在性的结果。

英文摘要:

In this paper, we study the set of homogeneous geodesics of a leftinvariant Finsler metric on Lie groups. We first give a simple criterion that characterizes geodesic vectors. As an application, we study some geometric properties of bi-invariant Finsler metrics on Lie groups. In particular a necessary and sufficient condition that left-invariant Randers metrics are of Berwald type is given. Finally a correspondence of homogeneous geodesics to critical points of restricted Finsler metrics is given. Then results concerning the existence homogeneous geodesics are obtained.
