Title: A quantitative note on dimension drop for harmonic measure
Time & Venue: 2026年1月29日（星期四）14: 30-16: 30 & N208
Abstract: In this talk, we present quantitative estimates for the dimension drop of harmonic measure on Ahlfors regular boundaries. By decoupling the geometric non-flatness into boundary deviation and porosity, we identify two distinct regimes for the critical dimension threshold S0.
