Abstract
The object of the present paper is to study N(${\kappa}$)-quasi Einstein manifolds. Existence of N(${\kappa}$)-quasi Einstein manifolds are proved. Physical example of N(${\kappa}$)-quasi Einstein manifold is also given. Finally, Weyl-semisymmetric N(${\kappa}$)-quasi Einstein manifolds have been considered.
Keywords
quasi Einstein manifolds; N(${\kappa}$)-quasi Einstein manifolds; pseudo Ricci symmetric spacetimes; conformal curvature tensor;
