Doubly warped product CR-submanifolds in a locally conformal kaehler space form

Recently, the present authors considered doubly warped product
CR-submanifolds in a locally conformal Kaehler manifold and got some
inequalities about the length of the second fundamental form ([14]).
In this report, we obtain an inequality of the mean curvature of a doubly
warped product CR-submanifold in a locally conformal Kaehler space form.
Then, we consider the equality case of this inequality.
