arXiv:1305.5993
Abstract
In this paper we show that for an invariant metric on a homogeneous Finsler manifold , induced by an invariant Riemannian metric and an invariant vector field , the vector is a geodesic vector of if and only if it is a geodesic vector of . Then we give some conditions such that under them, an arbitrary vector is a geodesic vector of if and only if it is a geodesic vector of . Finally we give an explicit formula for the flag curvature of bi-invariant metrics on connected Lie groups.
