Justin Moore Cornell University Keynote Title: A finitely presented group of piecewise projective homeomorphisms Abstract: I will describe a finitely presented subgroup of Monod¢s group of piecewise projective homeomorphisms of the real line. This in particular provides a new example of a finitely presented group which is nonamenable and yet does not contain a nonabelian free subgroup. Our example is moreover torsion free. This is joint work with Yash Lodha. |
