Bushy pseudocharacters and group actions on quasitrees

Álvaro Martínez-Pérez

Algebraic & Geometric Topology 12 (2012) 1721–1739
Abstract

Given a group acting on a graph quasi-isometric to a tree, we give sufficient conditions for a pseudocharacter to be bushy. We relate this with the conditions studied by Bestvina and Fujiwara on their work on bounded cohomology and obtain some results on the space of pseudocharacters.
