On a Classification of Almost C(α)‐Manifolds

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, pseudosymmetric and Ricci pseudosymmetric almost C(α)‐manifold are studied. For an almost C(α)‐manifold, Riemann pseudosymmetric, Riemann Ricci pseudosymmetric, Ricci pseudosymmetric, projective pseudosymmetric, projective Ricci pseudosymmetric, concircular pseudosymmetric, and concircular Ricci pseudosymmetric cases are considered and ...

LP‐Kenmotsu Manifolds Admitting η‐Ricci Solitons and Spacetime

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In the present paper, LP‐Kenmotsu manifolds admitting η‐Ricci solitons have been studied. Moreover, some results for η‐Ricci solitons in LP‐Kenmotsu manifolds in the spacetime of general relativity have also been proved. Through a nontrivial example, we have given a proof for the existence of η‐Ricci solitons in a 5‐dimensional LP‐Kenmotsu manifold.

On a Semi-symmetric Metric Connection in an Almost Kenmotsu Manifold with Nullity Distributions [PDF]

open access: yes, 2016
summary:We consider a semisymmetric metric connection in an almost Kenmotsu manifold with its characteristic vector field $\xi $ belonging to the $(k,\mu )^{\prime }$-nullity distribution and $(k,\mu )$-nullity distribution respectively.

Totally umbilical proper slant submanifolds of para-Kenmotsu manifold

open access: yesCubo, 2019
In this paper, we study slant submanifolds of a para-Kenmotsu manifold. We prove that totally umbilical slant submanifold of a para-Kenmotsu manifold is either invariant or anti-invariant or dimension of submanifold is 1 or the mean curvature vector H of

Conformal η-Ricci soliton in Lorentzian para Kenmotsu manifolds

open access: yesGulf Journal of Mathematics, 2023
The objective of the present paper is to study conformal η-Ricci soliton on Lorentzian Para-Kenmotsu manifolds with some curvature conditions. We study Concircular curvature tensor, Quasi conformal curvature tensor, Codazi type of Ricci tensor and cyclic parallel Ricci tensor in Lorentzian Para-Kenmotsu manifolds.

On the existence of para-Kenmotsu manifolds

open access: yes, 2022
This note provides a quite obvious observation that the condition (2.7), which is a part of the original definition of the so-called para-Kenmotsu manifolds [9], does not make sense, and thus this concept is void. So, it is proved that the para-Kenmotsu manifolds does not exist under the condition mentioned above.

On generalized projective curvature tensor of para-Kenmotsu manifolds

open access: yesMiskolc Mathematical Notes, 2023
Summary: The object of the present paper is to generalize projective curvature tensor of para-Kenmotsu manifold with the help of a new generalized (0,2) symmetric tensor \(\mathcal{Z}\) introduced by \textit{C. A. Mantica} and \textit{Y. J. Suh} [Int. J. Geom. Methods Mod. Phys. 9, No. 1, 1250004, 21 p. (2012; Zbl 1244.53019)].

On para-Kenmotsu manifolds

open access: yesFilomat, 2018
In this paper we study para-Kenmotsu manifolds. We characterize this manifolds by tensor equations and study their properties. We are devoted to a study of ?-Einstein manifolds. We show that a locally conformally flat para-Kenmotsu manifold is a space of constant negative sectional curvature -1 and we prove that if a para-Kenmotsu manifold ...
