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

For a stable curve of genus $g\ge 2$ and simple Lie algebra of type A or C, we show that the conformal blocks algebra $\mathcal{A}$ on ${\bar{\mathcal{M}}}_g$ 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.
