Bushy pseudocharacters and group actions on quasi-trees

By Álvaro Martínez-Pérez

Abstract

Given a group acting on a graph quasi-isometric to a tree, we give sufficent conditions for a pseudocharacter to be bushy. We relate this with the conditions studied by M. Bestvina and K. Fujiwara on their work on bounded cohomology and obtain some results on the space of pseudocharacters.Comment: 13 pages, 3 figure
