Half-lightlike submanifolds,There are two cases of codimension 2 lightlike submanifolds M since for this type the dimension of their radical distribution Rad. is either one or two. A codimension 2 lightlike submanifold is called half-lightlike [147] if dim(Rad .)=1. The objective of this chapter is to present up-to-date results of this sub-case.作者: AWRY 時間: 2025-3-23 12:12 作者: Postmenopause 時間: 2025-3-23 15:24
