题目：A criterion of nonparabolicity by the Ricci curvature.

报告人：丁青 教授（复旦大学）

摘要：A complete manifold is said to be nonparabolic if it does admit a positive Green's function. To find a sharp geometric criterion for the paranolicity/nonparabolicity is an  attractive question inside the function theory on Riemannian manifolds.  In this talk, we present a new criterion for the nonparabolicity of a complete manifold by the Ricci curvature.
