Abstract

In this paper, we investigate the converse of the Tan-Xu theorem, which states that the naturally reductive property of a Riemannian metric is inherited by a naturally reductive (α1,α2)(\alpha_1,\alpha_2)-metric, and we show that, under certain conditions, the converse also holds. We also examine the relationship between geodesic vector fields on homogeneous Riemannian spaces and homogeneous (α1,α2)(\alpha_1,\alpha_2)-spaces. Finally, we construct left-invariant (α1,α2)(\alpha_1,\alpha_2)-metrics on the tangent bundle of Lie groups using left-invariant Randers metrics on the base Lie group, and study their geometric relations.
