We give examples, investigate the geometry of distributions and obtain necessary and sufficient conditions for the induced connection on these submanifolds to be metric connection. We also check the existence of screen transversal lightlike submanifolds in indefinite Sasakian manifolds.eninfo:eu-repo/semantics/closedAccessIndefinite sasakian manifoldLightlike submanifoldScreen transversal lightlike submanifoldArticle1823153362-s2.0-78649522774Q3
