Gromov hyperbolic spaces and the sharp isoperimetric constant
Stefan Wenger
In this article we exhibit the largest constant in a quadratic isoperimetric inequality which ensures that a geodesic metric space is Gromov hyperbolic. As a particular consequence…

Characterizations of metric trees and Gromov hyperbolic spaces
Stefan Wenger
In a recent paper Chatterji and Niblo proved that a geodesic metric space is Gromov hyperbolic if and only if the intersection of any two closed balls has uniformly bounded eccentr…
