We show that the Riemannian geometry of a tangent sphere bundle of a Riemannian manifold (M,g) of constant radius r reduces essentially to the one of unit tangent sphere bundle of a Riemannian manifold equipped with the respective induced Sasaki metrics. Further, we provide some applications of this theorem on the η-Einstein tangent sphere bundles and certain related topics to the tangent sphere bundles.
Abstract
We show that the Riemannian geometry of a tangent sphere bundle of a Riemannian manifold (M,g) of constant radius r reduces essentially to the one of unit tangent sphere bundle of a Riemannian manifold equipped with the respective induced Sasaki metrics. Further, we provide some applications of this theorem on the η-Einstein tangent sphere bundles and certain related topics to the tangent sphere bundles.
