The escape phenomenon in open manifolds with
nonnegative Ricci curvature
Abstract: We start with a simple phenomenon in an open manifold
M with nonnegative Ricci curvature: the set of all minimal
representing geodesic loops of
π1(M,p) may not be
contained in any bounded sets of M. We will talk about how this escape
phenomenon is related to the algebraic structure of fundamental groups
and the metric structure of asymptotic cones. Part of this talk is
joint work with Guofang Wei.
