SUMMARY:Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:TYRONE GHASWALA\, UNIVERSITY OF MANITOBA\n\n\"Mapping class gro
 ups\, coverings\, braids and groupoids\"\n\nGiven a finite-sheeted\, possi
 bly branched covering space between\nsurfaces\, it's natural to ask how th
 e mapping class group of the\ncovering surface relates to the mapping clas
 s group of the base\nsurface. In this talk\, we will take a journey throug
 h this question\nfor surfaces with boundary. It will feature appearances f
 rom the\nfundamental groupoid\, the Birman-Hilden theorem\, the Burau\nrep
 resentation and new embeddings of the braid group in mapping class\ngroups
 .
