Title: Width estimate and doubly warped product
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 µ-bubble method.
