η-Einstein nearly Kenmotsu manifolds
Asian-European Journal of Mathematics, 2019In this paper, we showed that an [Formula: see text]-Einstein nearly Kenmotsu manifold with projective curvature tensor [Formula: see text], and conharmonic curvature tensor [Formula: see text], satisfy the conditions [Formula: see text] and [Formula: see text], respectively.

ON CERTAIN CURVATURE PROPERTIES OF KENMOTSU MANIFOLDS
JP Journal of Geometry and Topology, 2017Let \(M^n\), \(n=2m+1\), be an almost contact metric manifold with structure tensor fields consisting of a \((1,1)\)-tensor field \(\phi\), a 1-form \(\eta\), a vector field \(\xi\) and a Riemannian metric \(g\) satisfying, \(\phi^2X=-X+\eta(X)\xi\), \(\eta(\xi)=1\) and \(g(\phi X,\phi Y)=g(X,Y)-\eta(X)\eta(Y)\).

Some transformations on Kenmotsu manifolds
SUT Journal of Mathematics, 2013Summary: The present paper deals with certain transformations on a Kenmotsu manifold. We study infinitesimal \(CL\)-transformations and also \(CL\)-transformations on a Kenmotsu manifold and obtain a new tensor field which is invariant under such a transformation.

On the Kenmotsu Hypersurfaces of Special Hermitian Manifolds
Siberian Mathematical Journal, 2004Summary: We consider almost contact metric hypersurfaces of almost Hermitian manifolds of class \(W_3\) (in the Gray-Hervella terminology, see \textit{A. Gray} and \textit{L. M. Hervella} [Ann. Mat. Pura Appl. 123, 35--58 (1980; Zbl 0444.53032)]).

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

On ?-Kenmotsu manifolds satisfying certain conditions
2010The object of this paper is to study ?-Kenmotsu manifolds which can be derived from almost contact Riemannian manifolds satisfying some certain conditions. We first examine the generalized recurrent ?-Kenmotsu manifolds, and next we give some relations about Ricci semi-symmetric and D-conformal curvature tensors.
