초록

We study the geometry of lightlike submanifoldsof a semi-Riemannian manifold. The purpose of this paperis to prove two singular theorems for irrotational lightlike submanifolds$M$ of a semi-Riemannian space form $\bar{M}(c)$ admitting a semi-symmetricnon-metric connection such that the structure vector field of $\bar{M}(c)$is tangent to $M$.
