On cylindrically bounded -Hypersurfaces of
G. Pacelli Bessa, Silvana M. Costa
We show that -hypersurfaces of contained in a vertical cylinder and with Ricci curvature with strong quadratic decay have mean curvature $| H|…
A note on the first eigenvalue of spherically symmetric manifolds
Cleon S. Barroso, G. Pacelli Bessa
We give lower and upper bounds for the first eigenvalue of geodesic balls in spherically symmetric manifolds. These lower and upper bounds are -dependent on the metric coeff…
On compact CMC-Hypersurfaces of
Gregorio Pacelli Bessa, J. Fabio Montenegro
Let be the set of all closed -hypersurfaces , where is a simply connected complete Riemannian -manifold wi…
Complete subamanifolds of with finite topology
G. Pacelli Bessa, L. Jorge, J. Fabio Montenegro
We show that a complete -dimensional immersed submanifold of with is properly immersed and have finite topology, where is an s…
Foliations and Chern-Heinz inequalities
J. L. M. Barbosa, G. Pacelli Bessa, J Fabio Montenegro
We extend the Chern-Heinz inequalities about mean curvature and scalar curvature of graphs of -functions to leaves of transversally oriented codimension one -foliatio…
Lower bounds for the first Laplacian eigenvalue of geodesic balls of spherically symmetric manifolds
Gregorio Pacelli Bessa, Cleon S. Barroso
We obtain lower bounds for the first Laplacian eigenvalues of geodesic balls of spherically symmetric manifolds. These lower bounds are only dependent on the metric coeffic…
