The Existence of Two Homogeneous Geodesics in Finsler Geometry

The existence of a homogeneous geodesic in homogeneous Finsler manifolds was positively answered in previous papers. However, the result is not optimal. In the present paper, this result is refined and the existence of at least two homogeneous geodesics in any homogeneous Finsler manifold is proved. In a previous paper, examples of Randers metrics which admit just two homogeneous geodesics were constructed, which shows that the present result is the best possible.

Riemannian generalized C-spaces with homogeneous geodesics

We investigate homogeneous geodesics in a class of homogeneous spaces G/K' called generalized C-spaces. We give necessary conditions so that a G-invariant metric on G/K' is a g.o. metric.
