Let $X$ be a K3 surface with Beauville–Voisin class $d4c_X\in \operatorname{CH}_0(X)$, and let $\mathscr{X}\to X$ be a twist with twisted Beauville–Voisin class…

Let $X\subset\mathbb{P}^5$ be a smooth cubic fourfold, let $\mathcal{A}_X$ be its K3 category, and let $(S,\alpha)$ be a twisted K3 surface, with $\alpha\in\operatorname{Br}(S)$. T…

Let $(X,\alpha)$ be a twisted K3 surface, where $\alpha$ is a Brauer class, and let $X'$ be an untwisted Fourier–Mukai partner of $X$. For a Hodge isometry … consider the pullback…
