摘  要：This talk is about when the fundamental group of an open manifold with nonnegative Ricci curvature is finitely generated. We discuss recent results, including the case where the universal cover has a stable almost?splitting at infinity, and the four?dimensional case where it is noncollapsed (joint with Xian-Tao Huang).
