摘  要：We give some examples of open manifolds with positive Ricci curvature. These examples give negative answers to two open problems. One is about the properness of the Busemann function at some point, and the other one regards the singular set of Ricci limit spaces. This is joint work with Guofang Wei.

摘  要：We study the fundamental groups of open manifolds with nonnegative Ricci curvature through the equivariant asymptotic geometry of the universal covers. We go through some sketches of the proofs to see how this method works.
