亏格为8的泛K3曲面的合理性

Rationality of the universal K3 surface of genus 8

Daniele Di Tullio

摘要:

本文的目的是证明14阶极化$ K3 $曲面族的合理性。这是通过用立方四倍的模空间加上四次涡卷的数据来识别它来实现的。最后证明了最后一个模空间是有理的,因为它在具有$k \leq n$的$ k $ -稳定有理簇上具有$\mathbb P^n$ -丛的自然结构.

英文摘要:

The aim of the present paper is to prove the rationality of the universal family of polarized $ K3 $ surfaces of degree 14. This is achieved by identifying it with the moduli space of cubic fourfolds plus the data of a quartic scroll. The last moduli space is finally proved to be rational since it has a natural structure of $\mathbb P^n$-bundle over a $ k $-stably rational variety with $k \leq n$.
