Geometry of Nonholonomic Kenmotsu Manifolds

Izvestiya of Altai State University, 2021
The concept of the intrinsic geometry of a nonholonomic Kenmotsu manifold M is introduced. It is understood as the set of those properties of the manifold that depend only on the framing  of the D^ distribution D of the manifold M, on the parallel transformation of vectors belonging to the distribution D along curves tangent to this distribution.

HYPERBOLIC KENMOTSU MANIFOLD ADMITTING A NEW TYPE OF SEMI-SYMMETRIC NON-METRIC CONNECTION

Facta Universitatis Series Mathematics and Informatics
In this work, we study a new type of semi-symmetric non-metric connection on hyperbolic Kenmotsu manifold. Some Riemannian curvature’s characteristics on hyperbolic Kenmotsu manifold are investigated. The properties of semi-symmetric, locally ϕ-symmetric

*-Ricci-Yamabe soliton on Kenmotsu manifold with torse forming potential vector field

Filomat
The goal of the present paper is to deliberate *-Ricci-Yamabe soliton, whose potential vector field is torse-forming on the Kenmotsu manifold. Here, we have shown the nature of the soliton and found the scalar curvature when the manifold admitting ...

Ricci soliton and Ricci almost soliton within the framework of Kenmotsu manifold

Carpathian Mathematical Publications, 2019
First, we prove that if the Reeb vector field $\xi$ of a Kenmotsu manifold $M$ leaves the Ricci operator $Q$ invariant, then $M$ is Einstein. Next, we study Kenmotsu manifold whose metric represents a Ricci soliton and prove that it is expanding ...

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.

On para-Kenmotsu manifolds

Filomat, 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 \phi-Recurrent Kenmotsu Manifolds

Turkish Journal of Mathematics, 2009
The object of this paper is to study phi-recurrent Kenmotsu manifolds. Also three-dimensional locally phi-recurrent Kenmotsu manifolds have been considered. Among others it is proved that a locally phi-recurrent Kenmotsu spacetime is the Robertson-Walker spacetime. Finally we give a concrete example of three-dimensional Kenmotsu manifold.
