A characterization of Clifford torus

Universidade Federal de Campina Grande

We extend a previous sharp upper bound of the first strong stability eigenvalue due to Alías et al. [1] for the context of closed submanifold immersed with nonzero parallel mean curvature vector field in the Euclidean sphere and, through this result, we obtain a new characterization for the Clifford torus.
