On the conharmonic and concircular curvature tensors of almost C($\lambda $) Manifolds

Abstract

The object of the present paper is to characterize certain curvature conditions on conharmonic and concircular
curvature tensors on almost C($\lambda $) manifolds. In this paper we study conharmonically flat, $\xi $-conharmonically
flat, concircularly flat and $\xi $-concircularly flat almost C($\lambda $) manifolds.
