The Tits alternative for CAT(0) cubical complexes
Michah Sageev, Daniel T. Wise
We prove a Tits alternative theorem for groups acting on CAT(0) cubical complexes. Namely, suppose that is a group for which there is a bound on the orders of its finite subgro…
Quasi-actions on trees II: Finite depth Bass-Serre trees
Lee Mosher, Michah Sageev, Kevin Whyte
This paper addresses questions of quasi-isometric rigidity and classification for fundamental groups of finite graphs of groups, under the assumption that the Bass-Serre tree of th…
Maximally symmetric trees
Lee Mosher, Michah Sageev, Kevin Whyte
We characterize the ``best'' model geometries for the class of virtually free groups, and we show that there is a countable infinity of distinct ``best'' model geometries in an app…
Quasi-actions on trees I. Bounded valence
Lee Mosher, Michah Sageev, Kevin Whyte
Given a bounded valence, bushy tree T, we prove that any cobounded quasi-action of a group G on T is quasiconjugate to an action of G on another bounded valence, bushy tree T'. Thi…
Quasi-actions on trees: research announcement
Lee Mosher, Michah Sageev, Kevin Whyte
We develop a battery of tools for studying quasi-isometric rigidity and classification problems for splittings of groups. The techniques work best for finite graphs of groups where…
