报告摘要  Abstract

We will start this talk from the definition and some properties of convergence in Gromov-Hausdroff distance and then concentrate on the Gromov-Hausdorff limits of a sequence of complete $n$-manifolds with lower Ricci curvature bound, which is called Ricci limit spaces. We will show that if a Ricci limit space contains a point that its tangent cones are same and isometric to a line, then it is a one dimensional topological manifold.
