A product of trees as universal space for hyperbolic groups

Sergei Buyalo, Viktor Schroeder

Published 2005-09-15Version 1

We show that every Gromov hyperbolic group $\Ga$ admits a quasi-isometric embedding into the product of $(n+1)$ binary trees, where $n=\dim\di\Ga$ is the topological dimension of the boundary at infinity of $\Ga$.
