In this article, we obtain a gap property of energy densities of harmonic maps from a closed Riemannian manifold to a Grassmannian and then, use it to Gaussian maps of some submanifolds to get a gap property of the second fundamental forms.
Classification : 53C43, 58E20
Keywords: Grassmannian; Gaussian map; mean curvature; the second fundamental form
