Homotopy type of free group character varieties

Ana Casimiro, Carlos Florentino, Sean Lawton +1

Let G be a real reductive algebraic group with maximal compact subgroup K, and let F be a rank r free group. Here, we summarize the construction of a natural strong deformation ret…

Connectedness of Higgs bundle moduli for complex reductive Lie groups

Oscar García-Prada, André Oliveira

We carry an intrinsic approach to the study of the connectedness of the moduli space $M_{G}$ of $G$ -Higgs bundles, over a compact Riemann surface, when $G$ is a complex red…

Topology of Moduli Spaces of Free Group Representations in Real Reductive Groups

Ana Casimiro, Carlos Florentino, Sean Lawton +1

Let $G$ be a real reductive algebraic group with maximal compact subgroup $K$ , and let $F_{r}$ be a rank $r$ free group. We show that the space of closed orbits in $\mathrm{Hom}(F_r,…
