On Kenmotsu Manifolds Satisfying Certain Pseudosymmetry Conditions

The object of this paper is to study fi-Kenmotsu manifolds which can be derived from almost contact Riemannian manifolds satis- fying some certain conditions. We flrst examine the generalized recur- rent fi-Kenmotsu manifolds, and next we give some relations about Ricci semi-symmetric and D-conformal curvature tensors. We show that Ricci semi-symmetric fi-Kenmotsu manifolds are also Einstein manifolds. Fur- thermore, we prove that the scalar curvature of fi-Kenmotsu manifolds with ·-parallel Ricci tensors is constant. We conclude the paper with an example on fi-Kenmotsu manifolds.

On alpha-Kenmotsu manifolds satisfying certain conditions.

In this paper, we study conharmonic curvature tensor in Kenmotsu manifolds with respect to semi-symmetric metric connection and also characterize conharmonically flat, conharmonically semisymmetric and ϕ-conharmonically flat Kenmotsu manifolds with respect to semi-symmetric metric connection.

Some classes of Kenmotsu manifolds with respect to semi-symmetric metric connection

The object of the present paper is to introduce the notion of weakly φ-Ricci symmetric Kenmotsu manifolds and study characteristic properties of locally φ-Ricci symmetric and φ-recurrent spaces. AMS Subject Classification: 53C15, 53C25, 53D15
