Abstract
Let G be a semisimple linear algebraic group defined over the field ℂ, and let C be an irreducible smooth complex projective curve of genus at least three. We compute the Brauer group of the smooth locus of the moduli space of semistable principal G-bundles over C. We also compute the Brauer group of the moduli stack of principal G-bundles over C.
