Abstract: We considered submanifolds in statistical manifolds of constant curvatures by using Oprea’s optimization method, and obtained some geometric inequalities involving the generalized normalized δ-Casorati curvatures. We gave the upper bound and the lower bound of the normalized scalar curvature of the submanifolds, respectively, and the properties of submanifolds satisfying the equality cases.

Key words: statistical manifold, submanifold, generalized normalized δ-Casorati curvature, inequality
