On $N(k)$ mixed quasi Einstein manifolds and some global properties

Abstract: In this paper we have studied quasi conformally flat, conharmonically flat and projectively flat $N(k)$-mixed quasi Einstein manifold, Ricci-semi symmetric $N(k)$-mixed quasi Einstein manifold $N(k)-(MQE)_n$, $(n>3)$ and studied some properties on it.
