Warped cones, (non-)rigidity, and piecewise properties, with a joint appendix with Dawid Kielak
Damian Sawicki
We prove that if a quasi-isometry of warped cones is induced by a map between the base spaces of the cones, the actions must be conjugate by this map. The converse is false in gene…

Straightening warped cones
Damian Sawicki, Jianchao Wu
We provide the converses to two results of J. Roe (Geom. Topol. 2005): first, the warped cone associated to a free action of an a-T-menable group admits a fibred coarse embedding i…

Super-expanders and warped cones
Damian Sawicki
For a Banach space , we show that any family of graphs quasi-isometric to levels of a warped cone is an expander with respect to if and only if the induced $…
