Abstract:In this talk, I will review the research on the fundamental groups on noncompact manifolds with nonnegative Ricci curvature. And 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 contant
