We construct a three-parameter family of contact metric structures on the unit tangent sphere
bundle T 1 M of a Riemannian manifold M and we study some of their special properties …

In this paper, we consider spaces M of Riemannian metrics on a closed manifold M. In the
case where the manifold M is equipped with a symplectic or contact structure, we consider …

We characterize two-point homogeneous spaces, locally symmetric spaces, C and B-spaces
via properties of the standard contact metric structure of their unit tangent sphere bundle …
