We will discuss some ideas on how to determine the rational homotopy type of some moduli stacks of principal $G$-bundles on an algebraic curve over the complex numbers. This relies on a good notion of homotopy types of associated topological stacks and an analysis of the Haefliger-Brown-Szarba model for the rational homotopy type of mapping spaces. This is work in progress with U. Bujis (Barcelona). |
