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 classical Rauzy-Veech induction for studying actions of surface type. As an application, we prove that a tree in the boundary of Outer space is free and indecomposable if and only if its dual lamination is minimal up to diagonal leaves. Our main result generalizes [BFH97, Proposition 1.8] as well as the main result… 
Algebraic laminations for free products and arational trees
This work is the first step towards a description of the Gromov boundary of the free factor graph of a free product, with applications to subgroup classification for outer automorphisms. We extend
INVARIANT LAMINATIONS FOR IRREDUCIBLE AUTOMORPHISMS OF FREE GROUPS
For every atoroidal iwip automorphism $\phi$ of $F_N$ (i.e. the analogue of a pseudo-Anosov mapping class) it is shown that the algebraic lamination dual to the forward limit tree $T_+(\phi)$ is
Algebraic Ending Laminations and Quasiconvexity
We explicate a number of notions of algebraic laminations existing in the literature, particularly in the context of an exact sequence $$1\to H\to G \to Q \to 1 $$ of hyperbolic groups. These
Rips Induction: Index of the dual lamination of an $\R$-tree
Let $T$ be a $\R$-tree in the boundary of the Outer Space CV$_N$, with dense orbits. The $Q$-index of $T$ is defined by means of the dual lamination of $T$. It is a generalisation of the
Reducing systems for very small trees
We study very small trees from the point of view of reducing systems of free factors, which are analogues of reducing systems of curves for a surface lamination; a non-trivial, proper free factor $F
Stretching factors, metrics and train tracks for free products
In this paper we develop the metric theory for the outer space of a free product of groups. This generalizes the theory of the outer space of a free group, and includes its relative versions. The
The boundary of the free splitting graph and the free factor graph
We show that the Gromov boundary of the free factor graph for the free group Fn with n>2 generators is the space of equivalence classes of minimal very small indecomposable projective Fn-trees
Cocycle superrigidity from higher rank lattices to $\mathrm{Out}(F_N)$
We prove a rigidity result for cocycles from higher rank lattices to $\mathrm{Out}(F_N)$ and more generally to the outer automorphism group of a torsion-free hyperbolic group. More precisely, let $G$
Cannon–Thurston fibers for iwip automorphisms of FN
TLDR
It is proved that for any $\phi$, the map $\hat \iota$ is finite-to-one and that the preimage of every point of $\partial G_\phi$ has cardinality $\le 2N$.
The visual boundary of hyperbolic free-by-cyclic groups
Let $\phi$ be an atoroidal outer automorphism of the free group $F_n$. We study the Gromov boundary of the hyperbolic group $G_{\phi} = F_n \rtimes_{\phi} \mathbb{Z}$. We explicitly describe a family

On indecomposable trees in the boundary of outer space
Let T be an $${\mathbb{R}}$$-tree, equipped with a very small action of the rank n free group Fn, and let H ≤ Fn be finitely generated. We consider the case where the action $${F_n \curvearrowright
ℝ‐trees and laminations for free groups II: the dual lamination of an ℝ‐tree
We define a dual lamination for any isometric very small FN‐action on an ℝ‐tree T. We obtain an Out (FN)‐equivariant map from the boundary of the outer space to the space of laminations. This map
Actions of finitely generated groups on R-trees
We study actions of finitely generated groups on $\bbR$-trees under some stability hypotheses. We prove that either the group splits over some controlled subgroup (fixing an arc in particular), or

Let F be a free group of rank N ≥ 2, let μ be a geodesic current on F and let T be an $${\mathbb{R}}$$-tree with a very small isometric action of F. We prove that the geometric intersection number

IRREDUCIBLE AUTOMORPHISMS OF $F_{n}$ HAVE NORTH–SOUTH DYNAMICS ON COMPACTIFIED OUTER SPACE
We show that if an automorphism of a non-abelian free group $F_n$ is irreducible with irreducible powers, it acts on the boundary of Culler–Vogtmann’s outer space with north–south dynamics: there are
The rank of actions on ${R}$-trees
For n > 2, let Fn denote the free group of rank n. We define a total branching index z for a minimal small action of Fn on an R-tree. We show i < 2n 2, with equality if and only if the action is
