»ã±¨ÌáÒª£ºThe Ricci shrinker plays a significant role in studying the short-time singularities of the Ricci flow. In this talk, we shall address the question "Which Ricci shrinker is rigid in the moduli space?" We will present some recent rigidity theorems stating that some model spaces have no nearby Ricci shrinker in the Gromov-Hausdorff topology.
