Submanifolds with nonpositive extrinsic curvature

Universidadade de Sao Paulo

In this talk we will present the main results of a work in collaboration with S. Canevari and G. M. de Freitas. More precisely, we prove that complete submanifolds, on which the weak Omori-Yau maximum principle for the Hessian holds, with low codimension and bounded by cylinders of small radius must have points rich in large positive extrinsic curvature. The lower the codimension is, the richer such points are. The smaller the radius is, the larger such curvatures are. This work unifies and generalizes several previous results on submanifolds with nonpositive extrinsic curvature.
