Abstract : We study totally umbilical half lightlike submanifolds of an indefinite Kaehler manifold with a quarter-symmetric metric connection. We obtain some conditions for a half lightlike submanifold of an indefinite Kaehler manifold with a quarter-symmetric metric connection to be a product manifold. We also derive the expression for induced Ricci type tensor $\mathcal{R}^{(0, 2)}$ of such a half lightlike submanifold and obtain conditions for $\mathcal{R}^{(0, 2)}$ to be symmetric.
