DESCRIPTION:Yash Lodha (EPFL)\nIn 2012 Monod introduced examples of groups
  of piecewise projective\nhomeomorphisms which are not amenable and which 
 do not contain free subgroups\, and in 2013\nLodha and Moore introduced ex
 amples of finitely presented groups with the same property. In this talk w
 e discuss the normal subgroup structure\, and in particular the commutator
  subgroup structure of these groups. The main technique used in our work i
 s a theorem of Higman from 1954.\nThis is joint work with Burillo and Reev
 es.
