Abstract

In this paper we study mixed generalized quasi-Einstein manifold satisfying some curvature conditions like K.Ric = 0, C.Ric = 0, N.Ric = 0, where K, Ric, C and N denote the Reimannian curvature tensor, Ricci tensor, conformal curvature tensor and concircular curvature tensor and obtain some interesting and fruitful results on it.
