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…
The geometry of surface-by-free groups
Benson Farb, Lee Mosher
We show that every word hyperbolic, surface-by-(noncyclic) free group Gamma is as rigid as possible: the quasi-isometry group of Gamma equals the abstract commensurator group Comm(…
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…
On the asymptotic geometry of abelian-by-cyclic groups
Benson Farb, Lee Mosher
A finitely presented, torsion free, abelian-by-cyclic group can always be written as an ascending HNN extension Gamma_M of Z^n, determined by an n x n integer matrix M with det(M)…
Problems on the geometry of finitely generated solvable groups
Benson Farb, Lee Mosher
A survey of problems, conjectures, and theorems about quasi-isometric classification and rigidity for finitely generated solvable groups.
