For this purpose, the bounded sectional curvature is introduced and some special submanifolds of r-lightlike submanifolds of a semi-Riemannian manifold are investigated.trinfo:eu-repo/semantics/openAccesscurvature; lightlike submanifold; semi-Riemannian manifoldArticleQ2WOS:000391539700004Q12-s2.0-84958156178
