The Recognition Theorem for Out(F_n)
Mark Feighn, Michael Handel
Our goal is to find dynamic invariants that completely determine elements of the outer automorphism group $\Out(F_n)$ of the free group of rank . To avoid finite order phe…

Commensurations of Out(F_n)
Benson Farb, Michael Handel
Let $\Out(F_n)$ denote the outer automorphism group of the free group with . We prove that for any finite index subgroup $Γ<\Out(F_n)$, the group $\Aut(Γ)$ is isomorphic…

Axes in Outer Space
Michael Handel, Lee Mosher
We develop a notion of axis in the Culler--Vogtmann outer space X_r of a finite rank free group F_r, with respect to the action of a nongeometric, fully irreducible outer automorph…
