Multiplicative preprojective algebra conjecture. For every non-Dynkin quiver, the corresponding properties—including 2-Calabi–Yau-ness, primeness, flatness in $q$, and the asserted…

Let $Q$ be a connected non-Dynkin quiver and let $q\in (\mathbb{C}^\times)^{Q_0}$. Write $\Lambda^q(Q)$ for the multiplicative preprojective algebra of $Q$ with parameter $q$. 2-Ca…
