Hypersurfaces in a quasi Kahler manifold.

Okumura gave a necessary and sufficient condition for an oriented real hypersurface of a Kahler manifold to be a contact metric manifold with respect to the naturally induced almost contact metric structure. In this paper, we discuss an oriented hypersurface of a quasi Kahler manifold and give a necessary and sufficient condition for such a hypersurface to be a quasi contact metric manifold with respect to the naturally induced almost contact metric structure and we provide an application.
