Abstract :
We consider N(k)-quasi Einstein manifolds satisfying the conditions R(Xi;X) H = 0, H(Xi;X) S = 0, P(Xi;X) H = 0, R(Xi;X) . P = 0 and P bar(Xi;X) S = 0 where H, P and P bar denote the conharmonic curvature tensor, the projective curvature tensor and pseudo projective curvature tensor, respectively.
