Abstract

In this paper, we study invariant, slant andscreen slant lightlike submanifolds of indefinite para-Sasakianmanifolds. We obtain necessary and sufficient conditions forexistence of slant and screen slant lightlike submanifolds ofindefinite para-Sasakian manifolds and also provide non-trivialexamples of such submanifolds. We obtain integrability conditionsof distributions D and RadTM on screen slant lightlikesubmanifolds of indefinite para-Sasakian manifold. Further weobtain sufficient condition for induced connection on screen slantlightlike submanifolds of indefinite para-Sasakian manifold to bemetric connection.
