We study two types of $1$-lightlike submanifolds, so-called lightlike hypersurface and half lightlike submanifold, of an indefinite trans-Sasakian manifold $\bar{M}$ admitting non-metric $\theta$-connection. We prove that there exist no such two types of $1$-lightlike submanifolds of an indefinite trans-Sasakian manifold $\bar{M}$ admitting non-metric $\theta$-connections.
Abstract
We study two types of $1$-lightlike submanifolds, so-called lightlike hypersurface and half lightlike submanifold, of an indefinite trans-Sasakian manifold $\bar{M}$ admitting non-metric $\theta$-connection. We prove that there exist no such two types of $1$-lightlike submanifolds of an indefinite trans-Sasakian manifold $\bar{M}$ admitting non-metric $\theta$-connections.
