We show that a lightlike hypersurface is totally geodesic if and only if it is locally symmetric. Also, we show that a lightlike Hypersurface of Misplaced & is totally geodesic under some restrictions. Finally, we give some results ou Ricci curvature of a lightlike hypersurface to be symmetric.eninfo:eu-repo/semantics/openAccessOn lightlike hypersurfaces of a semi-Riemannian space formArticle27228329731676
