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

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