Brauer group of moduli of Higgs bundles and connections

Abstract

Given a compact Riemann surface $X$ and a semisimple affine algebraic group $G$ defined over $\mathbb{C}$, there are moduli spaces of Higgs bundles and of connections associated to $(X,G)$. We compute the Brauer group of the smooth locus of these varieties.
