摘要:

We obtain the Omori-Yau maximum principle on complete properly immersed submanifolds with the mean curvature satisfying certain condition in complete Riemannian manifolds whose radial sectional curvature satisfies some decay condition, which generalizes our previous results in [17]. Using this generalized maximum principle, we give an estimate
on the mean curvature of properly immersed submanifolds in Hn ×R? with the image under the projection on Hn contained in a horoball and the corresponding situation in hyperbolic space. We also give other applications of the generalized maximum principle.
