Some New Results on Trans‐Sasakian Manifolds

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we classify trans‐Sasakian manifolds which are realized as real hypersurfaces in a complex space form. We also investigate trans‐Sasakian manifolds whose Reeb vector fields are harmonic‐Killing. The above results bring some new characterizations for the property of trans‐Sasakian 3‐manifolds.

Magnetic and slant curves in Kenmotsu manifolds [PDF]

open access: yesSurveys in Mathematics and its Applications, 2020
Motivated by the recent studies of the magnetic curves in quasi-Sasakian, Sasakian, and Cosymplectic manifolds, in this article we investigate the magnetic trajectories with respect to contact magnetic fields in Kenmotsu manifolds. Moreover, we study the

On Generalized D-Conformal Deformations of Certain Almost Contact Metric Manifolds

open access: yesMathematics, 2019
In this work, we consider almost contact metric manifolds. We investigate the generalized D-conformal deformations of nearly K-cosymplectic, quasi-Sasakian and β -Kenmotsu manifolds.

η-Ricci Solitons on Kenmotsu 3-Manifolds

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2018
In the present paper we study η-Ricci solitons on Kenmotsu 3-manifolds. Moreover, we consider η-Ricci solitons on Kenmotsu 3-manifolds with Codazzi type of Ricci tensor and cyclic parallel Ricci tensor.

A Note on LP-Kenmotsu Manifolds Admitting Conformal Ricci-Yamabe Solitons

open access: yesInternational Journal of Analysis and Applications, 2023
In the current note, we study Lorentzian para-Kenmotsu (in brief, LP-Kenmotsu) manifolds admitting conformal Ricci-Yamabe solitons (CRYS) and gradient conformal Ricci-Yamabe soliton (gradient CRYS).

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

On an (ε,δ)-trans-Sasakian structure; pp. 20–28 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2012
In this paper we investigate (ε,δ)-trans-Sasakian manifolds which generalize the notion of (ε)-Sasakian and (ε)-Kenmotsu manifolds. We prove the existence of such a structure by an example and we consider φ-recurrent, pseudo-projectively flat and ...

open access: yesFrontiers in Physics, 2022
The goal of the present study is to study the ∗-η-Ricci soliton and gradient almost ∗-η-Ricci soliton within the framework of para-Kenmotsu manifolds as a characterization of Einstein metrics.
