Abstract

Let G be a real reductive algebraic group with maximal compact subgroup K,
and let Fr be a rank r free group. Here, we summarize the construction of a natural strong deformation retraction from the space of closed orbits in Hom(Fr,G)/G to the orbit space Hom(Fr,K)/K. In particular, these spaces have the same homotopy type.
