Link to the paper: "Fundamental Groups and the Milnor Conjecture", https://arxiv.org/abs/2303.15347 > It was conjectured by Milnor in 1968 that the fundamental group of a complete manifold with nonnegative Ricci curvature is finitely generated. The main result of this paper is a counterexample, which provides an example M7 with Ric ≥ 0 such that π1(M) = Q/Z is infinitely generated.
