Shape of Thurston’s filling systole subset in surface moduli space

报告人： Yue Gao from Anhui Normal University

摘要： In this talk, I am going to talk about the sparseness of Thurston’s subset. Sparseness is a geometric concept on Thurston’s subset first raised by Anderson-Parlier-Pettet in 2016. We have proved the sparseness of Thurston’s subset in the sense of Teichmüller distance and Weil-Petersson distance. More precisely, most surfaces in genus g surface moduli space have Teichmüller distance $\frac{1}{5}\log\log g$ and Weil-Petersson distance $0.6521(\sqrt{\log g}−\sqrt{7\log\log g})$ to the Thurston’s subset.
