论文摘要
我们构建了两个K3 [2]类型的投影Hyper-Kähler四倍的示例，并具有交替的A7组的作用，使其成为最对称的Hyper-Kähler四倍。它们被认为是所谓的Double EPW Sextics，这使我们能够建造一个明确的Gushel-Mukai三倍的家族。
We construct two examples of projective hyper-Kähler fourfolds of K3[2]-type with an action of the alternating group A7, making them some of the most symmetric hyper-Kähler fourfolds. They are realized as so called double EPW sextics and this allows us to construct an explicit family of irrational Gushel-Mukai threefolds.
