The  19th  Annual    R.  A.  Blyth  Lectures  in  Mathematics  

Abstract:      3-­‐manifolds   can   be   built   up   by   a   process   of   gluing   along  surfaces,   and   a   good   quantitative   understanding   of   this  can   help   us   study   the   geometric   structures   that   these  manifolds   admit.   This   leads   to   a   detailed   study   of   the  mapping  class  group  of  a  surface  and  its  coarse  geometry.      I  will  discuss  the  history  of   this  area  over   recent   (and  not  so   recent)   years,   and   hopefully   give   an   overview   of   the  current  state,  where  a  number  of  question  marks  remain.
