SOME NOTES ON KENMOTSU MANIFOLD [PDF]
Facta Universitatis, Series: Mathematics and Informatics, 2021 In the present paper, we deal with a Kenmotsu manifold $M$. Firstly, we study the notion of torse-forming vector field on such a manifold. Then, we investigate some curvature conditions such as $Q.\mathcal{M}=0$ and $C.Q=0$ on such a manifold and obtain some necessary conditions for such a manifold given as to be Einstein and $\eta-$Einstein.

On connections with torsion on nonholonomic para-Kenmotsu manifolds
Дифференциальная геометрия многообразий фигур, 2023 The concept of a nonholonomic para-Kenmotsu manifold is introduced. A nonholonomic para-Kenmotsu manifold is a natural generalization of a para-Kenmotsu manifold; the distribution of a nonholonomic para-Kenmotsu manifold does not need to be involutive.

Communications in Mathematics, 2023 The object of this paper is to study generalized φ-recurrent almost Kenmotsu manifolds with characteristic vector field ξ belonging to (k, µ)-nullity distribution. We have showed that these manifolds reduce to Kenmotsu manifolds with scalar curvature-1.

A Kenmotsu metric as a conformal $\eta$-Einstein soliton
Karpatsʹkì Matematičnì Publìkacìï, 2021 The object of the present paper is to study some properties of Kenmotsu manifold whose metric is conformal $\eta$-Einstein soliton. We have studied certain properties of Kenmotsu manifold admitting conformal $\eta$-Einstein soliton.

Non-holonomic Kenmotsu manifolds equipped with generalized Tanaka — Webster connection
Дифференциальная геометрия многообразий фигур, 2021 А non-holonomic Kenmotsu manifold equipped with a connection analogous to the generalized Tanaka — Webster connection, is considered. The studied connection is obtained from the generalized Tanaka — Webster connection by replacing the first structural ...

Acta et Commentationes Universitatis Tartuensis de Mathematica, 2022 In the present paper, we introduce a new class of structures on an even dimensional differentiable Riemannian manifold which combines, well known in literature, the Sasakian and Kenmotsu structures simultaneously. The structure will be called a Sasaki–Kenmotsu structure by us.

On a Class of α-Para Kenmotsu Manifolds [PDF]
Mediterranean Journal of Mathematics, 2014 The purpose of this paper is to classify $α$-para Kenmotsu manifolds $M^3$ such that the projection of the image of concircular curvature tensor $L$ in one-dimensional linear subspace of $T_{p}(M^{3})$ generated by $ξ_{p}$ is zero.
