Abstract:
Following on from the previous talk, I will discuss how quantitative K-theory sheds light on the geometric significance of the index of elliptic operators by allowing one to refine the classical connection between uniform positive scalar curvature and vanishing higher index. I will also discuss the link with Gromov's band width conjecture. This is based on previous joint work with Zhizhang Xie and Guoliang Yu.
