Abstract

In this paper, we prove two characterization theorems for real half lightlike submanifold (M,g,S(TM)) of an indefinite Kaehler manifold <TEX>$\bar{M}$</TEX> or an indefinite complex space form <TEX>$\bar{M}$</TEX>(c) subject to the conditions : (a) M is totally umbilical in <TEX>$\bar{M}$</TEX>, or (b) its screen distribution S(TM) is totally umbilical in M.

keywords
