报告人：黄显涛 教授（中山大学）

地 点：海纳苑2幢203

摘 要：In this talk, I will first review the research on the fundamental groups on noncompact manifolds with nonnegative Ricci curvature, then I will introduce a recent joint work with Hongzhi Huang which says that if M is a 4-dimensional open manifold with nonnegative Ricci curvature, and its universal cover has Euclidean volume growth, then the fundamental group of M is finitely generated and contains an abelian subgroup whose index is bounded by a universal constant.
