讲座主题：Width estimate and doubly warped product
讲座摘要: In this talk, Dr. Zhu 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.
