Characterizations of higher rank hyperbolicity
Tommaso Goldhirsch, Urs Lang
The concept of Gromov hyperbolicity manifests itself in many different ways. With only mild assumptions on the underlying metric space, the spectrum of equivalent properties includ…

Lipschitz Chain Approximation of Metric Integral Currents
Tommaso Goldhirsch
Every integral current in a locally compact metric space can be approximated by a Lipschitz chain with respect to the normal mass, provided that Lipschitz maps into can be…
