On Lightlike Submanifolds of Poly-Norden Semi-Riemannian Manifolds

Abstract

In this paper, we introduce and examine invariant and semi-invariant lightlike submanifolds of a poly-Norden semi-Riemannian manifold. Also, we obtain some examples of such types submanifolds and study the conditions for both integrability and totally geodesic foliation description of distributions.
