The mimimally displaced set of an irreducible automorphism of $F_{N}$ is co-compact

Stefano Francaviglia, Armando Martino, Dionysios Syrigos

We study the minimally displaced set of irreducible automorphisms of a free group. Our main result is the co-compactness of the minimally displaced set of an irreducible automorphi…

The minimally displaced set of an irreducible automorphism is locally finite

Stefano Francaviglia, Armando Martino, Dionysios Syrigos

We prove that the minimally displaced set of a relatively irreducible automorphism of a free splitting, situated in a deformation space, is uniformly locally finite. The minimally…

Stabiliser of an Attractive Fixed Point of an IWIP Automorphism of a free product

Dionysios Syrigos

For a group $G$ of finite Kurosh rank and for some arbiratily free product decomposition of $G$ , $G = H_{1} * H_{2} * ... * H_{r} * F_{q}$ , where $F_{q}$ is a finitely generated…
