Moduli spaces and the algebra of conformal blocks

Abstract

For a classical simple and simply connected group GG, let MG,ω\mathcal{M}_{G,\omega} be the moduli space of ω\omega-semistable parabolic GG-bundles on a complex smooth projective curve of genus gg. We prove two results in this article: (1) MG,ω\mathcal{M}_{G,\omega} is of Fano type when g3g\geq 3; (2) the algebra of conformal blocks on any nn-pointed stable curve for a classical simple Lie algebra is finitely generated.
