Measure transfer and -adic developments for subshifts

Nicolas Bédaride, Arnaud Hilion, Martin Lustig

Based on previous work of the authors, to any -adic development of a subshift a "directive sequence" of commutative diagrams is associated, which consists at every level $n…

The measure transfer for subshifts induced by a morphism of free monoids

Nicolas Bédaride, Arnaud Hilion, Martin Lustig

Every non-erasing monoid morphism induces a {\em measure transfer map} between the me…

Invariant measures on finite rank subshifts

Nicolas Bédaride, Arnaud Hilion, Martin Lustig

In this note we show that for any subshift of finite -rank every invariant measure is determined by its values on finitely many cylinders. Under mild conditions these cy…

Tower power for -adics

Nicolas Bédaride, Arnaud Hilion, Martin Lustig

We explain and restate the results from our recent paper arXiv:1503.08000.v3 in standard language for substitutions and -adic systems in symbolic dynamics. We then produce as ra…

The visual boundary of hyperbolic free-by-cyclic groups

Yael Algom-Kfir, Arnaud Hilion, Emily Stark

Let be an atoroidal outer automorphism of the free group . We study the Gromov boundary of the hyperbolic group . We explicitly describe a…

Topological substitutions and Rauzy fractals

Nicolas Bédaride, Arnaud Hilion, Timo Jolivet

We consider two families of planar self-similar tilings of different nature: the tilings consisting of translated copies of the fractal sets defined by an iterated function system,…

Graph towers, laminations and their invariant measures

Nicolas Bédaride, Arnaud Hilion, Martin Lustig

In this paper we present a combinatorial machinery, consisting of a graph tower and vector towers on , which allows us to ef…

Growth and order of automorphisms of free groups and free Burnside groups

Rémi Coulon, Arnaud Hilion

We prove that an outer automorphism of the free group is exponentially growing if and only if it induces an outer automorphism of infinite order of free Burnside groups with suffic…

Ergodic currents dual to a real tree

Thierry Coulbois, Arnaud Hilion

Let be an -tree in the boundary of Outer space with dense orbits. When the free group $\FN$ acts freely on , we prove that the number of projective classes of ergodic cu…

The hyperbolicity of the sphere complex via surgery paths

Arnaud Hilion, Camille Horbez

Handel and Mosher have proved that the free splitting complex FS for the free group is Gromov hyperbolic. This is a deep and much sought-after result, since it establishes FS as a…

Botany of irreducible automorphisms of free groups

Thierry Coulbois, Arnaud Hilion

We give a classification of iwip outer automorphisms of the free group, by discussing the properties of their attracting and repelling trees.

Indecomposable -trees and minimal laminations

Thierry Coulbois, Arnaud Hilion, Patrick Reynolds

We extend the techniques of [CH] to build an inductive procedure for studying actions in the boundary of the Culler-Vogtmann Outer Space, the main novelty being an adaptation of he…

Free group automorphisms with parabolic boundary orbits

Arnaud Hilion

For , we show that there exist automorphisms of the free group which have a parabolic orbit in . In fact, we exhibit a technology for producing infinit…

Geometric realizations of two dimensional substitutive tilings

Nicolas Bedaride, Arnaud Hilion

We define 2-dimensional topological substitutions. A tiling of the Euclidean plane, or of the hyperbolic plane, is substitutive if the underlying 2-complex can be obtained by itera…

Rips Induction: Index of the dual lamination of an -tree

Thierry Coulbois, Arnaud Hilion

Let be a -tree in the boundary of the Outer Space CV, with dense orbits. The -index of is defined by means of the dual lamination of . It is a generalisation…

-trees, dual laminations, and compact systems of partial isometries

Thierry Coulbois, Arnaud Hilion, Martin Lustig

Let $\FN$ be a free group of finite rank , and let be an -tree with a very small, minimal action of $\FN$ with dense orbits. For any basis $\CA$ of $\FN$ there ex…

Non-unique ergodicity, observers' topology and the dual algebraic lamination for -trees

Thierry Coulbois, Arnaud Hilion, Martin Lustig

We continue in this article the study of laminations dual to very small actions of a free group F on R-trees. We prove that this lamination determines completely the combinatorial…

-trees and laminations for free groups III: Currents and dual -tree metrics

Thierry Coulbois, Arnaud Hilion, Martin Lustig

This is the third of a series of three articles where we introduce laminations for the free-groups. We explore here the link between currents and laminations and prove that the sit…

-trees and laminations for free groups II: The dual lamination of an -tree

Thierry Coulbois, Arnaud Hilion, Martin Lustig

This is the second part of a series of three articles which introduce laminations for free groups (see math.GR/0609416 for the first part). Several definition of the dual laminatio…

-trees and laminations for free groups I: Algebraic laminations

Thierry Coulbois, Arnaud Hilion, Martin Lustig

This paper is the first of a sequence of three papers, where the concept of an -tree dual to a measured geodesic lamination in a hyperbolic surface is generalized to arb…
