Geometry & Topology

Exact sequences of braid and mapping class groups

Jon Berrick (Yale-NUS College)

Wednesday 9 December 2015 from 12:00–13:00 in Carslaw 535A

Please join us for lunch after the talk!

Abstract: This talk describes a cluster of work, mostly at NUS, on exact sequences that relate braid groups, mapping class groups of surfaces, and homotopy groups of spheres. I'll try to make it accessible to non-specialists.
