Title: Mapping class groups, coverings, braids and groupoids
Abstract: Given a finite-sheeted, possibly branched covering space between surfaces, itâ€™s natural to ask how the mapping class group of the covering surface relates to the mapping class group of the base surface. In this talk, we will take a journey through this question for surfaces with boundary. It will feature appearances from the fundamental groupoid, the Birman-Hilden theorem, the Burau representation and new embeddings of the braid group in mapping class groups.
This is joint work with Alan McLeay.
