The SL(3, C)-representation variety R of a free group F r arises naturally by considering surface group representations for a surface with boundary. There is an SL(3,C)-action on the coordinate ring of R by conjugation. The geometric points of the subring of invariants of this action is an affine variety X. The points of X parametrize isomorphism classes of completely reducible representations. We show the coordinate ring C[X] is a complex Poisson algebra with respect to a presentation of F r… 
Obtaining the One-Holed Torus from Pants: Duality in an SL(3,C)-Character Variety
The SL(3,C)-representation variety R of a free group F arises naturally by considering surface group representations for a surface with boundary. There is a SL(3,C)-action on the coordinate ring of
Gluing Formulas for Volume Forms on Representation Varieties of Surfaces
. Let Σ g,n be a compact oriented surface with genus g ≥ 2 bordered by n circles. Due to Witten, the twisted Reidemeister torsion coincides with a power of the Atiyah-Bott-Goldman-Narasimhan
Holomorphic volume forms on representation varieties of surfaces with boundary
For closed and oriented hyperbolic surfaces, a formula of Witten establishes an equality between two volume forms on the space of representations of the surface in a semisimple Lie group. One of the
Compact connected components in relative character varieties of punctured spheres
We prove that some relative character varieties of the fundamental group of a punctured sphere into the Hermitian Lie groups $\mathrm{SU}(p,q)$ admit compact connected components. The representations
Extended Goldman symplectic structure in Fock-Goncharov coordinates.
Given an oriented graph on a punctured Riemann surface of arbitrary genus, we define a canonical symplectic structure over the set of flat connections on the dual graph, and show that it is invariant
Surfaces, braids, Stokes matrices, and points on spheres
Moduli spaces of points on $n$-spheres carry natural actions of braid groups. For $n=0$, $1$, and $3$, we prove that these symmetries extend to actions of mapping class groups of positive genus
Moduli spaces of real projective structures on surfaces
These notes grew out of our learning and applying the methods of Fock and Goncharov concerning moduli spaces of real projective structures on surfaces with ideal triangulations. We give a
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
Invariants of pairs in (4,ℂ) and (3,1)
We describe a minimal global coordinate system of order 30 on the SL(4,C)-character variety of a rank 2 free group. Using symmetry within this system, we obtain a smaller collection of 22 coordinates
Dimension of representation and character varieties for two and three-orbifolds.
We consider varieties of representations and characters of 2 and 3-dimensional orbifolds in semisimple Lie groups, and we focus on computing their dimension. For hyperbolic 3-orbifolds, we consider

Spin networks and SL(2,C)-Character varieties
Denote the free group on 2 letters by F_2 and the SL(2,C)-representation variety of F_2 by R=Hom(F_2,SL(2,C)). The group SL(2,C) acts on R by conjugation. We construct an isomorphism between the
The deformation theory of representations of fundamental groups of compact Kähler manifolds
AbstractLet Γ be the fundamental group of a compact Kähler manifold M and let G be a real algebraic Lie group. Let ℜ(Γ, G) denote the variety of representations Γ → G. Under various conditions on ρ ∈
Group systems, groupoids, and moduli spaces of parabolic bundles
Moduli spaces of homomorphisms or, more generally, twisted homomorphisms from fundamental groups of surfaces to compact connected Lie groups, were connected with geometry through their identification
For a Riemann surface with one puncture we consider moduli spaces of flat connections such that the monodromy transformation around the puncture belongs to a given conjugacy class with the property
$SL_n$-character varieties as spaces of graphs
An SL_n-character of a group G is the trace of an SL_n-representation of G. We show that all algebraic relations between SL_n-characters of G can be visualized as relations between graphs (resembling
Finite dimensional representations of algebras
Let R be a ring, K a field, and n a natural number. We will be concerned with the following type of questions: (a) Classify the representations of R in (hO, (or n dimensional representations). (b)
The ring of invariants of matrices
We denote by M(n) the space of all n × n-matrices with their coefficients in the complex number field C and by G the group of invertible matrices GL(n, C). Let W = M(n) i be the vector space of
