چکیده

In this article we give a geometric interpretation of the Hitchin component T (Σ) ⊂ Rep(π1(Σ),PSL4(R)) of a closed oriented surface of genus g ≥ 2. We show that representations in T (Σ) are precisely the holonomy representations of properly convex foliated projective structures on the unit tangent bundle of Σ. From this we also deduce a geometric description of the Hitchin component T (Σ, Sp4(R)) of representations into the symplectic group.

Simple Root Flows for Hitchin Representations

Anosov representations ([19, 15]) from a hyperbolic group to a semi-simple Lie group are characterized by their dynamical nature. In the context of projective Anosov representations, we [7] previously associated a metric Anosov flow to such a representation and showed that the (thermo)dynamical properties of this flow yield in turn new structures on the deformation space of these representation...

The existence totally reflexive covers

Let $R$ be a commutative Noetherian ring. We prove that  over a local ring $R$ every finitely generated $R$-module $M$ of finite Gorenstein projective dimension has a Gorenstein projective cover$varphi:C rightarrow M$ such that $C$ is finitely generated and the projective dimension of $Kervarphi$ is finite and $varphi$ is surjective.

Convex projective structures on Gromov–Thurston manifolds

Gromov and Thurston in [10] constructed, for each n 4, examples of compact n– manifolds which admit metrics of negative curvature, with arbitrarily small pinching constants, but do not admit metrics of constant curvature. We review these examples in Section 3. The main goal of this paper is to put convex projective structures on Gromov– Thurston examples. Suppose that  RP is an open subset and...
