Also we give sufficient and efficient conditions for screen invariant and screen anti invariant lightlike submanifold of a semi-Riemanniann product manifold to have non-degenerate planar normal sections.eninfo:eu-repo/semantics/closedAccessLightlike submanifoldssemi-Riemannian product manifoldsPlanar normal sectionScreen transversal lightlike submanifoldsArticle917077222652WOS:000412876600009N/A
