De U.C.Yildiz A.Mallick S.2024-08-042024-08-0420161221-8421https://hdl.handle.net/11616/91044The object of the present paper is to study N(k)-quasi-Einstein manifolds. Existence of N(k)-quasi Einstein manifolds is proved by a non-trivial example. Also some physical examples of N(k)-quasi-Einstein manifolds are given. We study an N(k)-quasi-Einstein manifold satisfying the curvature conditions C(?, X) · R = 0, R(?, X) · (formula present) = 0, and W (?, X) · S = 0, where R, C, (formula present) and S denote the Riemannian curvature tensor, the conformal curvature tensor, m-projective curvature tensor and Ricci tensor respectively. © 2016, Universitatii Al.I.Cuza din Iasi.
