ON SOME CLASSES OF NEARLY QUASI-EINSTEIN MANIFOLD

摘要

In this paper we have studied about nearly quasi-Einstein manifold satisfying some curvature conditions like K. Ric = 0. P.Ric = 0. C.Ric = 0. N.Ric = 0. W_2.Ric = 0 where K. Ric. P, C, N and W_2 denote the Reimannian curvature tensor, Ricci tensor, projective curvature tensor, conformal curvature tensor, concircular curvature tensor and W_2-curvature tensor and investigated some interesting and fruitful results on it.
