ALMOST KENMOTSU PSEUDO-RIEMANNIAN MANIFOLDS
Juanhua Liu and Ximin Liu
|
Abstract: In this paper, we study a class of differentiable manifolds admitting almost contact structures and pseudo-Riemannian metrics. A necessary and sufficient condition for an almost Kenmotsu pseudo-Riemannian metric manifold to be Kenmotsu manifold is obtained. Also, we characterize general D-homothetic deformation and other deformations of an almost Kenmotsu pseudo-Riemannian manifold. |
Keywords and phrases: almost Kenmotsu structure, pseudo-Riemannian metric, D-homothetic deformation, Ricci tensor. |
