From almost smooth spaces to RCD spaces

Speaker: Shouhei Honda, University of Tokyo

Location: Warren Weaver Hall 512

Date: Friday, September 26, 2025, 11 a.m.

Synopsis:

We provide various characterizations for a given almost smooth space to be an RCD space. Applications include a characterization of Einstein 4-orbifolds. We also discuss differences, at the technical level for applications, between Ricci limit and RCD. This talk is based on a joint work with Song Sun (Zhejiang University).
