Colloquium: Geometric Limits of Kähler–Ricci Flows and Ricci Shrinkers

Seminar| Institute of Mathematical Sciences

Time: Wednesday, November 4th, 2026,16:00-17:00

Location: IMS S408

Speaker: Yu Li, IGP-USTC


Abstract: In this talk, I will discuss the Gromov–Hausdorff convergence of compact volume-noncollapsed Kähler–Ricci flows at their first singular time. We prove uniqueness of the limit, identify its regular part with the complement of the null locus, and establish that its singular set has Hausdorff codimension at least four. We also discuss the geometry at infinity of Kähler–Ricci shrinkers, including uniform scalar curvature bounds and uniqueness of tangent cones. This is joint work with Junsheng Zhang.
