DESCRIPTION:TYRONE GHASWALA\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY O
 F\nWATERLOO\n\n\"Mapping class groups\, coverings\, braids and groupoids\"
 \n\nSuppose you are handed a finite sheeted (possibly branched) covering\n
 space between closed 2-manifolds by an eccentric mathematician.  A\nnatur
 al question to ask is what is the relationship between the\nmapping class 
 group of the covering surface and the mapping class\ngroup of the base sur
 face?
