# Harry Petyt: Large-scale geometry of mapping class groups

**Time: **

Zoom, meeting ID: 694 6016 6420 (password required)

**Lecturer: **
Harry Petyt (University of Bristol)

**Abstract:**

Mapping class groups have been a motivating example in topology and infinite group theory since Dehn. In recent years and with the advent of geometric group theory, there has been a lot of effort to understand what kind of nonpositive curvature properties they have. This talk will describe some of the background to these efforts and discuss some recent results.
