Abstract
In this paper we study invariant lightlike submanifolds of Lorentzian para-sasakian manifolds. We investigate geodesic CR-lightlike submanifolds of Lorentzian para-sasakian manifolds. We study screen CR-lightlike submanifolds of Lorentzian para-sasakian manifolds. Some necessary and sufficient conditions for mixed geodesic, totally geodesic,
D
¯
-geodesic and
D
ˊ
-geodesic contact CR-lightlike submanifolds and SCR-lightlike submanifolds are obtained.
