ON KENMOTSU MANIFOLDS

open access: yesJournal of the Korean Mathematical Society, 2005
Let \((M^n,\phi,\xi,\eta,g)\) be an \(n=2m+1\)-dimensional almost contact Riemannian manifold. If \((\nabla_X\phi)Y=-g(X,\phi Y)\xi-\eta(Y)\phi X\) and \(\nabla_X\xi=X-\eta(X)\xi\) then \((M^n,\phi,\xi,\eta,g)\) is called a Kenmotsu manifold. In the reviewed paper, the authors show that curvature conditions such as Ricci semisymmetry or Ricci ...

$$\varphi $$-Trajectories in Kenmotsu manifolds

Journal of Geometry, 2022
Let \(M =(M, \varphi, \xi, \eta, g)\) be an almost contact metric manifold with Levi-Civita connection \(\nabla\). A curve \(\gamma(s)\) in \(M\) is said to be a \(\varphi\)-trajectory if it satisfies \(\nabla_{\gamma\prime} \gamma\prime = q \varphi(\gamma\prime)\) for some constant \(q\) (called the charge).

On the Existence of Proper Nearly Kenmotsu Manifolds [PDF]

open access: yesMediterranean Journal of Mathematics, 2016
This is an expository paper, which provides a first approach to nearly Kenmotsu manifolds. The purpose of this paper is to focus on nearly Kenmotsu manifolds and get some new results from it. We prove that for a nearly Kenmotsu manifold is locally isometric to warped product of real line and nearly Kähler manifold. Finally, we prove that there exist no

Invariant submanifolds of f-Kenmotsu manifolds

International Journal of Geometric Methods in Modern Physics, 2022
In the present paper, we study the invariant submanifolds of [Formula: see text]-Kenmotsu manifolds. Firstly, we show that any invariant submanifold of [Formula: see text]-Kenmotsu manifold is again [Formula: see text]-Kenmotsu manifold and minimal. Then, we give some characterizations of totally geodesic submanifolds of [Formula: see text]-Kenmotsu ...
