Generalized Kenmotsu Manifolds

, 2016
In 1972, K. Kenmotsu studied a class of almost contact Riemannian manifolds which later are called a Kenmotsu manifold. In this paper, we study Kenmotsu manifolds with (2n + s)-dimensional s-contact metric manifold that we call generalized Kenmotsu ...

Generalized curvature tensor and the hypersurfaces of the Hermitian manifold for the class of Kenmotsu type

, 2023
This paper determined the components of the generalized curvature tensor forthe class of Kenmotsu type and established the mentioned class is{\eta}-Einstein manifold when the generalized curvature tensor is flat; theconverse holds true under suitable ...

Some Solitons on Lorentzian Para-Kenmotsu Manifolds

Sarajevo Journal of Mathematics
In this paper we study the nature of the Einstein soliton and $\eta $-Einstein soliton in the framework of Lorentzian para-Kenmotsu manifolds (briefly, LP-Kenmotsu manifolds). We find an expression for scalar curvature of LP-Kenmotsu manifolds admitting the Einstein soliton and $\eta $-Einstein soliton in various cases.

The Sasaki-Kenmotsu manifolds

, 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.

Ricci solitons in Kenmotsu manifolds.

, 2012
In this paper we study Ricci solitons in Kenmotsu manifolds. We consider quasi conformal, conharmonic and projective curvature tensors in a Kenmotsu manifold admitting Ricci solitons and prove the conditions for the Ricci solitons to be shrinking, steady

Geometric solitons in a $D$-homothetically deformed Kenmotsu manifold

, 2021
We consider almost Riemann and almost Ricci solitons in a $D$-homothetically deformed Kenmotsu manifold having as potential vector field a gradient vector field, a solenoidal vector field or the Reeb vector field of the deformed structure, and explicitly

Classification of totally umbilical slant submanifolds of a Kenmotsu manifold

, 2016
The purpose of this paper is to classify totally umbilical slant submanifolds of a Kenmotsu manifold. We prove that a totally umbilical slant submanifold M of a Kenmotsu manifold ?M is either invariant or anti-invariant or dimM = 1 or the mean ...

Pointwise pseudo-slant submanifolds of a Kenmotsu manifold

, 2017
In the present article, we have investigated pointwise pseudo-slant submanifolds of Kenmotsu manifolds and have sought conditions under which these submanifolds are warped products.
