Abstract: By using a new algebraic inequality, we established two inequalities for generalized normalized Casorati curvatures of submanifolds in a Bochner Kaehler manifold,which gave relationships between the normalized scalar curvatures and the extrinsic invariants Casorati curvatures of submanifolds.

Key words: slant submanifold, Casorati curvature, Bochner Kaehler manifold, Einstein manifold, inequality
