We obtain necessary and sufficient conditions for a half-lightlike submanifold of R-2(4) such that it has degenerate or nondegenerate planar normal sections.eninfo:eu-repo/semantics/openAccessHalf-lightlike submanifoldplanar normal sectionsArticle38476477710.3906/mat-1209-272-s2.0-84898939778Q2WOS:000338003700013Q4
