Hypersurfaces of two space forms and conformally flat hypersurfaces

S. Canevari, R. Tojeiro

We address the problem of determining the hypersurfaces $f : M^{n} \to Q_{s}^{n + 1} (c)$ with dimension $n \geq 3$ of a pseudo-Riemannian space form of dimension $n + 1$ , con…

Submanifolds with nonpositive extrinsic curvature

Samuel Canevari, Guilherme Machado de Freitas, Fernando Manfio

We prove that complete submanifolds, on which the Omori-Yau weak maximum principle for the Hessian holds, with low codimension and bounded by cylinders of small radius must have po…
