Abstract

In this paper, we focus on an almost contact metric manifold admitting a type of semi-symmetric nonmetric
connection. We find the expression for the curvature tensor of such a manifold. Furhermore, we
study the properties of the curvature tensor and the projective curvature tensor.

Keywords
