Bijective Quasi-Isometries of Amenable Groups

Group Theory 2007-05-23 v1

Abstract

Whyte showed that any quasi-isometry between non-amenable groups is a bounded distance from a bijection. In contrast this paper shows that for amenable groups, inclusion of a proper subgroup of finite index is never a bounded distance from a bijection.
