Abstract
We give lower bounds for the fundamental tone of open sets in submanifolds with locally bounded mean curvature in , where is an -dimensional complete Riemannian manifold with radial sectional curvature . When the immersion is minimal our estimates are sharp. We also show that cylindrically bounded minimal surfaces has positive fundamental tone.
