Title: "A nonamenable finitely presented group of piecewise projective homeomorphisms."
Speaker: Yash Lodha (EPFL)
Abstract: I will describe a finitely presented group of piecewise projective homeomorphisms of the real line. This provides a new example of a finitely presented group which is nonamenable and yet does not contain a nonabelian free subgroup. The example is torsion free and of type $$F_\infty$$. A portion of this is joint work with Justin Moore.
