报告摘要 Abstract:

In this talk, I will introduce Gromov's torical band width estimate for positive scalar curvature. In the setting of positive sectional curvature, Gromov conjectured that the 3 dimensional torical band width estimate can be improved and it is characterized by the doubly warped product model for standard round $3$-sphere. We will present a proof based on the $\mu$-bubble method.
