Generalized η-Ricci solitons on f-Kenmotsu 3-manifolds associated to the Schoutenvan Kampen connection [PDF]

AUT Journal of Mathematics and Computing
In this paper, we investigate f-Kenmotsu 3-dimensional manifolds admitting generalized η-Ricci solitons with respect to the Schouten-van Kampen connection.

Almost α-Cosymplectic Pseudo Metric Manifolds

Journal 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.

Nearly Kahler and nearly Kenmotsu manifolds

TURKISH 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.

Integrability Properties of Generalized Kenmotsu Manifolds

Владикавказский математический журнал, 2018
Статья посвящена обобщенным многообразиям Кенмоцу, а именно исследованию их свойств интегрируемости. Исследование ведется методом присоединенных G-структур, поэтому вначале построено пространство присоединенной G-структуры почти контактных метрических многообразий.

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

Open 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 ...

LP-Kenmotsu Manifolds Admitting Bach Almost Solitons

Universal 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}}

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. The structure will be called a Sasaki-Kenmotsu structure by us.

On nonexistence of Kenmotsu structure on аст-hypersurfaces of cosymplectic type of a Kählerian manifold

Дифференциальная геометрия многообразий фигур, 2019
Almost contact metric (аст-)structures induced on oriented hypersur­fa­ces of a Kählerian manifold are considered in the case when these аст-struc­tures are of cosymplectic type, i. e. the contact form of these struc­tu­res is closed. As it is known, the
