Index realization for automorphisms of free groups

We say that D respects the approximation property, or that D is approximable, if the interpretation of any term corresponds to the inductive interpretation of its B¨ohm tree, i.e..

This property, which is a particular instance of a very general notion due to Malcev, was introduced and studied in the group-theoretic setting by Gordon- Vershik [GV97] and St¨

The argument of the proof above actually shows the stronger result that for any given Nielsen-Thurston ordering of finite type ≺, there exists another finite-type

If Φ does not come from a pseudo-Anosov mapping class and if T Φ is geometric then Φ is called parageometric. For a parageometric iwip Φ, Guirardel [Gui05] and Handel and Mosher

Using the cluster reduction we define special type of cluster-pA mapping classes, called cluster Dehn twists, and prove that they have an asymptotic behavior of orbits on the

This property characterizes the non-spreading homeomorphisms of such a surface S: if a homeomorphism isotopic to the identity satises this property, then we will see that it is
