Study of New Curvature Tensors on Para Kenmotsu Manifold and Other Related Manifolds.

Abstract

he objective of this paper is to study a Para Kenmotsu manifold admitting the W7-curvature tensor. We will investigate the geometry of a Para Kenmotsu manifold when it is W7- at, W7-semisymmetric, W7-symmetric and W7-recurrent. Also, we will establish the necessary condition for a P-Kenmotsu manifold to be W7-irrotational
