Abstract

After brief introduction, we prove that a totally contact umbilical CR- lightlike submanifold is totally contact geodesic. We obtain a necessary and sufficient condition for a CR-lightlike submanifold to be an anti-invariant submanifold. Finally, we characterize a contact CR-lightlike submanifold of indefinite Sasakian manifold to be a contact CR-lightlike product

Keywords: indefinite Sasakian manifolds; lightlike submanifolds; contact CR-lightlike submanifolds; totally contact umbilical submanifolds
