On Kenmotsu manifolds satisfying certain curvature conditions

Abstract

The object of the present paper is to study some curvature conditions on Kenmotsu manifolds. Also, we classify Kenmotsu manifolds which satisfy P⋅C˜=0,C˜⋅C˜=0,Z˜⋅C˜=0,C˜⋅Z˜=0 and C⋅C˜=0, where P is the projective curvature tensor, Z˜ is the concircular curvature tensor, C˜ is the quasi-conformal curvature tensor and C is the conformal curvature tensor.
