Sobre H-hipersuperfÃcies compactas de N X R / H-hypersurfaces of N x R

Heloisa FrazÃo da Silva 13 July 2011 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Consideraremos F(N x R) o conjunto das H-hipersuperfÃcies fechadas M tal que M &#1057; N x R, onde N Ã uma variedade riemanniana simplesmente conexa com curvatura seccional limitada superiormente (KN &#8804; -k2 < 0). A partir daÃ, com o auxÃlio do Teorema de ComparaÃÃo do Hessiano mostraremos algumas desigualdades para estas subvariedades M &#1057; N x R com curvatura mÃdia constante HM. / Consider F(N x R) the set of closed hypersurfaces M such that M C N x R) where N is a simply connected riemannian manifold with sectional curvature bounded above (KN &#8804; -k2 < 0). Thereafter, with the aid of Hessian Comparison Theorem we show some inequalities for these submanifolds M &#1057; N x R with constant mean curvature HM.
