Characterizing rigid simplicial actions on trees

Gilbert Levitt

We extend Forester's rigidity theorem so as to give a complete characterization of rigid group actions on trees (an action is rigid if it is the only reduced action in its deformat…

Automorphisms of free groups have asymptotically periodic dynamics

Gilbert Levitt, Martin Lustig

We show that every automorphism of a free group of finite rank has {\it asymptotically periodic} dynamics on and its boundary : there exists a pos…
