ON LIGHTLIKE SUBMANIFOLDS OF A GRW SPACE-TIME
Kang, Tae Ho;

Abstract
This paper provides a study of lightlike submanifolds of a generalized Robertson-Walker (GRW) space-time. In particular, we investigate lightlike submanifolds with curvature invariance, parallel second fundamental forms, totally umbilical second fundamental forms, null sectional curvatures and null Ricci curvatures, respectively.
