On Lightlike Hypersurfaces of a Semi-Riemannian Space form
Lightlike Hypersurfaces Semi-Riemannian Space form
2010/3/1
In this paper, we study a Lightlike hypersurface of a semi-Riemann manifold. We show that a lightlike hypersurface is totally geodesic if and only if it is locally symmetric. Also, we show that a ligh...
