Ricciη-parallel trans-Sasakian 3-manifolds

Quaestiones Mathematicae, 2019
In this paper, we present a new characterization for a trans-Sasakian 3-manifold to be proper. More precisely, we prove that if a compact trans-Sasakian 3-manifold has -parallel Ricci operator, then the manifold is homothetic to a cosymplectic or a Sasakian 3-manifold or is of type (0; β ) with ∇ β = ξ ( β ) ξ.

On 3D Generalized Trans-Sasakian Manifold

International Electronic Journal of Geometry
In a 3-dimensional generalized trans-Sasakian manifold, explicit formula for Ricci operator, Ricci tensor and curvature tensor are obtained. In particular, expressions for Ricci tensor are obtained in a 3-dimensional generalized trans-Sasakian manifold in cases of the manifold being quasi-Einstein or generalized quasi-Einstein.
