Lightlike Hypersurfaces of Poly-Norden Semi-Riemannian Manifolds

Abstract

In this article, we initiate the study of lightlike hypersurfaces in a poly-Norden semi-Riemannian manifold. We introduce invariant and screen semi-invariant lightlike hypersurfaces of a poly-Norden semi- Riemannian manifold. Also, we give some examples of such hypersurfaces.

Keywords

• Almost poly-Norden structure
• poly-Norden manifold
• Lightlike hypersurface
