Abstract

The object of the present paper is to study N(k)-quasi Einstein manifolds. Existence of N(k)-quasi Einstein manifolds are proved by two non-trivial examples. Also a physical example of an N(k)-quasi-Einstein manifold is given. We study an N(k)-quasi-Einstein manifold satisfying the curvature conditions ˜Z(ξ,X)·S = 0, P(ξ,X)· ˜Z = 0, ˜Z(ξ,X)·P = 0, ˜Z(ξ,X)·C = 0 and P(ξ,X)· C = 0. Finally, we study Ricci-pseudosymmetric N(k)-quasi-Einstein manifolds. [ABSTRACT FROM AUTHOR]
