Abstract. In present paper we obtain a condition for an
invariant lightlike submanifold of indefinite Sasakian space form to
be of constant φ-sectional curvature. Then, we study contact
CR-lightlike submanifolds of (ε)-Sasakian manifolds extensively and
concluded with the study of totally contact umbilical contact CR-lightlike
submanifolds.
