Abstract
The object of the present paper is to study N($\small{{\kappa}}$)-quasi Einstein manifolds. Existence of N($\small{{\kappa}}$)-quasi Einstein manifolds are proved. Physical example of N($\small{{\kappa}}$)-quasi Einstein manifold is also given. Finally, Weyl-semisymmetric N($\small{{\kappa}}$)-quasi Einstein manifolds have been considered.
