Jin \cite{Jin4} defined a new connection on semi-Riemannian manifolds, which is a non-symmetric and non-metric connection. He said that this connection is an {\it $(\ell,\,m)$-type connection}. Jin also studied lightlike hypersurfaces of an indefinite trans-Sasakian manifold with an $(\ell, m)$-type connection in \cite{Jin4}. We study further the geometry of this subject. In this paper, we study generic lightlike submanifolds of an indefinite trans-Sasakian manifold endowed with an $(\ell, m)$-type connection.
Keywords: $(\ell, m)$-type connection, generic lightlike submanifold, indefinite trans-Sasakian structure
