Compactifications of moduli of $G$-bundles and conformal blocks

Abstract

For a stable curve of genus $g\geq 2$ and simple Lie algebra of type A or C, we show that the conformal blocks algebra $\mathcal{A}$ on $\overline{\mathcal{M}}_g$ is finitely generated and establish an explicit connection to Schmitt and Mu\~{n}oz-Casta\~{n}eda's compactification of the moduli space of $G$-bundles.
