Half lightlike submanifolds of an indefinite trans-Sasakian manifold with a non-metric phi-symmetric connection

초록

Jin (Bull Korean Math Soc 54(2): 619-632, 2017) introduced the notion of non-metric phi-symmetric connection on semi-Riemannian manifolds. He studied lightlike hypersurfaces of an indefinite Kaehler manifold with a non-metric phi-symmetric connection Jin (2017) and an indefinite trans-Sasakian manifold with a non-metric phi-symmetric connection (Jin in Bull Korean Math 53(6): 1771-1783, 2016). We study further the geometry of this subject. We study half lightlike submanifolds of an indefinite trans-Sasakian manifold with a non-metric phi-symmetric connection.
