One-dimensional actions of Higman's group

Abstract : We build a faithful action of Higman's group on the line by homeomorphisms, answering a question of Yves de Cornulier. As a by-product we obtain many quasimorphisms from Higman's group into the reals. We also show that every action by C-1-diffeomorphisms of Higman's group on the line or the circle is trivial.
