Some results on the p-fundamental tone estimates.

Resumo:

In this talk we estimate the p-fundamental tone of submanifolds in a Cartan-Hadamard manifold. First we obtain lower bounds for the p-fundamental tone of geodesic balls and submanifolds with bounded mean curvature. Moreover we provide the p-fundamental tone estimates of minimal submanifolds with certain conditions on the norm of the second fundamental form.
