Title: Examples of open manifolds with positive Ricci curvature and non-proper Busemann functions
Speaker: 潘佳垠教授 (Fields Institute & UC-Santa Cruz)

Abstract：We give the first example of an open manifold with positive Ricci curvature and a non-proper Busemann function at a point. This provides counterexamples to a well-known open question whether the Busemann function at a point of an open manifold with nonnegative Ricci curvature is proper. This is a joint work with Guofang Wei.
