Let Γ be a finitely generated group and G be a noncompact semisimple connected real Lie group with finite center. We consider the space $${\fancyscript X(\Gamma, G)}$$ of conjugacy classes of semisimple representations of Γ into G, which is the maximal Hausdorff quotient of $${{\rm Hom}(\Gamma, G)/G}$$ . We define the translation vector of $${g \in G}$$, with value in a Weyl chamber, as a natural refinement of the translation length of g in the symmetric space associated with G. We construct a… 
Maximal representations, non Archimedean Siegel spaces, and buildings
Let $\mathbb F$ be a real closed field. We define the notion of a maximal framing for a representation of the fundamental group of a surface with values in ${\rm Sp}(2n,\mathbb F)$. We show that
Wonderful compactification of character varieties
Using the wonderful compactification of a semisimple adjoint affine algebraic group G defined over an algebraically closed field k of arbitrary characteristic, we construct a natural compactification
Rigidity at infinity for the Borel function of the tetrahedral reflection lattice
Let $\Gamma$ be a non-uniform lattice of $PSL(2,\mathbb{C})$. To every representation $\rho:\Gamma \rightarrow PSL(n,\mathbb{C})$ it is possible to associate a numerical invariant $\beta_n(\rho)$,
Character varieties for real forms
Let $$\varGamma $$Γ be a finitely generated group and G a real form of $$\mathrm {SL}_n(\mathbb {C})$$SLn(C). We propose a definition for the G-character variety of $$\varGamma $$Γ as a subset of the
Higher laminations and affine buildings
We give a Thurston-like definition for laminations on higher Teichmuller spaces associated to a surface $S$ and a semi-simple group $G$ for $G-SL_m$ and $PGL_m$. The case $G=SL_2$ or $PGL_2$
On the Fock-Goncharov Moduli Space for Real Projective Structures on Surfaces: Cell Decomposition, Buildings and Compactification
Let S be a non-compact surface with empty boundary and negative Euler characteristic. Fock and Goncharov [30, 31] devise coordinate systems for the space of properly convex projective structures on S
Espaces de représentations complètement réductibles
It is proved that the space of completely reducible classes is the maximal Hausdorff quotient space for the conjugacy action of G on the representation space.
Positive crossratios, barycenters, trees and applications to maximal representations
Let $\Sigma:=\Gamma\backslash\mathbb H$ be a finite volume hyperbolic surface. We associate to any $\Gamma$-invariant positive crossratio defined on a dense subset of $\partial\mathbb H$ a canonical
Hitchin harmonic maps are immersions
In 1992, Hitchin used his theory of Higgs bundles to construct an important family of representations of the fundamental group of a closed, oriented surface of genus at least two into the split real
Finite order automorphisms of Higgs bundles: theory and application
We study the C∗ action on the moduli space of G-Higgs bundles. Focus is especially put on Higgs bundle which are not fixed points of the whole action but are fixed by a roots of unity subgroup of C∗.


Sous-groupes elliptiques de groupes lin eaires sur un corps valu e
Let n be a positive integer and F be a valuated field. We prove the following result: Let Γ be a subgroup of GLn(F) generated by a bounded subset, such that every element of Γ belongs to a bounded
Local rigidity of discrete groups acting on complex hyperbolic space
The superrigidity theorem of Margulis, see Zimmer [17], classifies finite dimensional representations of lattices in semi-simple Lie groups of real rank strictly larger than 1. It is a fundamental
Propriétés Asymptotiques des Groupes Linéaires
Abstract. Let G be a reductive linear real Lie group and $\Gamma$ be a Zariski dense subgroup. We study asymptotic properties of $\Gamma$ through the set of logarithms of the radial components of
Deformation Spaces Associated to Compact Hyperbolic Manifolds
In this paper we take a first step toward understanding representations of cocompact lattices in SO(n,1) into arbitrary Lie groups by studying the deformations of rational representations — see
Anosov flows, surface groups and curves in projective space
Note that in [10], W. Goldman gives a complete description of these connected components in the case of finite covers of PSL(2,R). In the case of PSL(2,R), two homeomorphic components, called
Espaces de représentations complètement réductibles
It is proved that the space of completely reducible classes is the maximal Hausdorff quotient space for the conjugacy action of G on the representation space.
Recently, there has been considerable interest in spaces of locally homogeneous (or geometric) structures on smooth manifolds, motivated by Thurston [6, 7]. If M is a smooth manifold, we will let
Conjugacy classes of $n$-tuples in Lie algebras and algebraic groups
Let G be a reductive algebraic group over an algebraically closed field F of characteristic zero and let L(G) be the Lie algebra of G. Then G acts on G by inner automorphisms and it acts on L(G) by
Quotients for algebraic group actions over non-algebraically closed fields.
We discuss two quotient objects. Given the group G and variety Fas above (with points in an algebraic closure of fc), one always has the invariant-theoretic quotient V//G (§1); then a reasonable
The word and Riemannian metrics on lattices of semisimple groups
Let G be a semisimple Lie group of rank ⩾2 and Γ an irreducible lattice. Γ has two natural metrics: a metric inherited from a Riemannian metric on the ambient Lie group and a word metric defined with
