Parageometric outer automorphisms of free groups
Michael Handel, Lee Mosher
We study those fully irreducible outer automorphisms phi of a finite rank free group F_r which are ``parageometric'', meaning that the attracting fixed point of phi in the boundary…
The expansion factors of an outer automorphism and its inverse
Michael Handel, Lee Mosher
A fully irreducible outer automorphism phi of the free group F_n of rank n has an expansion factor which often differs from the expansion factor of the inverse of phi. Nevertheless…
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…
Fiber respecting quasi-isometries of surface group extensions
Lee Mosher
Let S be a closed, oriented surface of genus at least 2, and consider the extension 1 -> pi_1 S -> MCG(S,p) -> MCG(S) -> 1, where MCG(S) is the mapping class group of S, and MCG(S,…
Homology and dynamics in quasi-isometric rigidity of once-punctured mapping class groups
Lee Mosher
In these lecture notes, we combine recent homological methods of Kevin Whyte with older dynamical methods developed by Benson Farb and myself, to obtain a new quasi-isometric rigid…
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…
