Resumen de Complete Hypersurfaces with Constant Mean Curvature in a Unit Sphere

Guoxin Wei

• By investigating hypersurfaces M n in the unit sphere S n+1(1) with constant mean curvature and with two distinct principal curvatures, we give a characterization of the torus S 1(a) × , where . We extend recent results of Hasanis et al. [5] and Otsuki [10].
