Details: Speaker: Arka Banerjee Title: Coarse cohomology of the complement Abstract: John Roe defined the notion of Coarse cohomology of a metric space that measures the behavior at infinity of a space: more specifically, it measures the way in which uniformly large bounded sets fit together. In my talk I will give a brief introduction to this theory and define a new notion called "Coarse cohomology of the complement." Time permitting, I will discuss some related results and applications.This talk is partly based on a joint work with Boris Okun. |
