K. Takegoshi, A VOLUME ESTIMATE FOR STRONG SUBHARMONICITY AND MAXIMUM PRINCIPLE ON COMPLETE RIEMANNIAN-MANIFOLDS, Nagoya Mathematical Journal, 151, 1998, pp. 25-36
A generalized maximum principle on a complete Riemannian manifold (M,
g) is shown under a certain volume growth condition of (M, g) and its
geometric applications are given.
