초록

In this paper, we study the connectedness at infinity of complete submanifolds by using the theory of p-harmonic function. For lower-dimensional cases, we prove that if M is a complete orientable noncompact hypersurface in Rn+1 and if delta-stability inequality holds on M, then M has only one p-nonparabolic end. It is also proved that if M-n is a complete noncompact submanifold in R-n vertical bar k with sufficiently small L-n norm of the traceless second fundamental form, then M has only one p-nonparabolic end. Moreover, we obtain a lower bound of the fundamental tone of the p Laplace operator on complete submanifolds in a Riemannian manifold.
