Ideal tubular hypersurfaces in real space forms
In this article we give a classification of tubular hypersurfaces in real space forms which are -ideal.
On an inequality of Oprea for Lagrangian submanifolds
We show that a Lagrangian submanifold of a complex space form attaining equality in the inequality obtained by Oprea in [8], must be totally geodesic.
