Title: Nonnegative Ricci curvature and escape rate gap

Abstract: Let MM be an open nn-manifold of nonnegative Ricci curvature and let pMp\in M. We show that if (M,p)(M,p) has escape rate less than some positive constant ϵ(n)\epsilon(n), that is, minimal representing geodesic loops of π1(M,p)\pi_1(M,p) escape from any bounded balls at a small linear rate with respect to their lengths, then π1(M,p)\pi_1(M,p) is virtually abelian.
