(12月21日）几何分析讨论班第十二次

题目：The asymptotic behavior of the dimension of spaces of harmonic functions with polynomial growth 报告人：黄显涛（中山大学）报告摘要: Suppose (M, g) is a noncompact Riemannian manifold with nonnegative Ricci curvature, and let hd(M) be the dimension of the space of harmonic functions with polynomial growth of growth order at most d. Colding and Minicozzi proved that hd(M) is finite. La...
