Some results on almost Kenmotsu manifolds [PDF]

open access: yes, 2020
First we consider almost Kenmotsu manifolds which satisfy Codazzi condition for $h$ and $\varphi h$, and we prove that in such cases the tensor $h$ vanishes.

LP-Kenmotsu Manifolds Admitting Bach Almost Solitons

open access: yesUniversal Journal of Mathematics and Applications
For a Lorentzian para-Kenmotsu manifold of dimension $m$ (briefly, ${(LPK)_{m}}$) admitting Bach almost soliton $(g,\zeta,\lambda)$, we explored the characteristics of the norm of Ricci operator. Besides, we gave the necessary condition for ${(LPK)_{m}}

η-Ricci solitons in Kenmotsu manifolds

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2019
The object of the present paper is to study generalized weakly symmetric and generalized weakly Ricci symmetric Kenmotsu manifolds whose metric tensor is η-Ricci soliton. The paper also aims to bring out curvature conditions for which η-Ricci solitons in

Pointwise pseudo-slant submanifolds of a Kenmotsu manifold

open access: yes, 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.

*-Ricci soliton on (κ, μ)′-almost Kenmotsu manifolds

open access: yesOpen Mathematics, 2019
Let (M, g) be a non-Kenmotsu (κ, μ)′-almost Kenmotsu manifold of dimension 2n + 1. In this paper, we prove that if the metric g of M is a *-Ricci soliton, then either M is locally isometric to the product ℍn+1(−4)×ℝn or the potential vector field is ...

Ricci solitons in Kenmotsu manifolds.

open access: yes, 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

Classification of totally umbilical slant submanifolds of a Kenmotsu manifold

open access: yes, 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 ...

The Sasaki-Kenmotsu manifolds

open access: yes, 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.
