In 2012 Monod introduced examples of groups of piecewise projective
homeomorphisms which are not amenable and which do not contain free subgroups, and in 2013
Lodha and Moore introduced examples of finitely presented groups with the same property. In this talk we discuss the normal subgroup structure, and in particular the commutator subgroup structure of these groups. The main technique used in our work is a theorem of Higman from 1954.
This is joint work with Burillo and Reeves.
