Work in the setting of Cohen–Macaulay rational singularities. Let $N=H^0(\mathcal{V}_X)$, where $\mathcal{V}_X$ is the object from the paper’s contraction and tilting setup, and le…

Assume the setting of Cohen–Macaulay rational singularities, and let $\Lambda$ and $\Lambda_{\mathrm{con}}$ be the algebras associated to the contraction setup. Let the Homological…
