The Z‐Tensor on Almost Co‐Kählerian Manifolds Admitting Riemann Soliton Structure

open access: yesAdvances in Mathematical Physics, Volume 2024, Issue 1, 2024.
A Riemann soliton (RS) is a natural generalization of a Ricci soliton structure on pseudo‐Riemannian manifolds. This work aims at investigating almost co‐Kählerian manifolds (ACKM) 2n+1 whose metrics are Riemann solitons utilizing the properties of the Z‐tensor.

Nearly Kahler and nearly Kenmotsu manifolds

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2018
Summary: We study the class of strict nearly Kenmotsu manifolds and prove that there is no Einstein manifold or locally symmetric or locally \(\phi\)-symmetric in this class of manifolds. We describe strict nearly Kenmotsu manifolds in low dimensions.

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 ...

On The Ricci Symmetry of Almost Kenmotsu Manifolds

open access: yesTamkang Journal of Mathematics, 2021
In the present paper, we characterize Ricci symmetric almost Kenmotsu manifolds under several constraints and proved that they are Einstein manifolds. As a consequence, we obtain several corollaries. Finally, an illustrative example is presented to verify our results.

Almost α-Cosymplectic Pseudo Metric Manifolds

open access: yesJournal of Mathematics, 2021
The main purpose of this paper is to study almost α-cosymplectic pseudo metric manifold satisfying certain η-parallel tensor fields. We first focus on the concept of almost α-cosymplectic pseudo metric manifold and its curvature properties.

η-Ricci solitons on nearly Kenmotsu manifolds

open access: yesAsian-European Journal of Mathematics, 2019
In this paper, we study the geometry and topology of [Formula: see text]-Ricci solitons satisfying Ricci-semisymmetry condition, [Formula: see text] condition and finally Einstein-semisymmetry condition on nearly Kenmotsu manifolds.
