Some transformations on Kenmotsu manifolds

SUT Journal of Mathematics, 2013
Summary: 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 ?-recurrent Kenmotsu manifolds

2009
The 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

2010
The 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.

Invariant Submanifolds of a Kenmotsu Manifold

2003
In this paper new results on invariant submanifolds of a Kenmotsu manifold are estabilshed. Also there are given the characterisations theorems for the η-parallel submanifolds of a Kenmotsu manifold.
