Principal bundles on 2-dimensional CW-complexes with disconnected structure group

André Oliveira

Given any topological group $G$ , the topological classification of principal $G$ -bundles over a finite CW-complex $X$ is long-known to be given by the set of free homotopy classes…

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…

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,…
