Peskine sixfolds and Debarre-Voisin fourfolds with associated cubic fourfolds

Corey Brooke, Laure Flapan, Sarah Frei +1

We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, t…

Equivariant Kuznetsov components for cubic fourfolds with a symplectic involution

Laure Flapan, Sarah Frei, Lisa Marquand

We study the equivariant Kuznetsov component $Ku_{G} (X)$ of a general cubic fourfold $X$ with a symplectic involution. We show that $Ku_{G} (X)$ is equivalent to the d…
