Rationality of Peskine varieties
We study the rationality of the Peskine sixfolds in P 9 . We prove the rationality of the Peskine sixfolds in the divisor D 3 , 3 , 10 inside the moduli space of Peskine sixfolds and we provide a cohomological condition which ensures the rationality of the Peskine sixfolds in the divisor D 1 , 6 , 1...

[(notation from Benedetti and Song (Divisors in the moduli space of Debarre-Voisin varieties,
http://arxiv.org/abs/2106.06859
, 2021)]. We conjecture, as in the case of cubic fourfolds containing a plane, that the cohomological condition translates into a cohomological and geometric condition involving the Debarre-Voisin hyperkähler fourfold associated to the Peskine sixfold. |
