In this talk, I will introduce Gromov’s torical band widthestimate for positive scalar curvature. In the setting of positive sectionalcurvature, Gromov conjectured that the 3-dimensional torical band widthestimate can be improved and it is characterized by the doubly warpedproduct model for standard round 3-sphere. We will present a proof basedon the u-bubble method.
