椭圆K3曲面上的稳定对

Stable pairs on elliptic K3 surfaces

Marcello Bernardara

摘要:

本文研究了带截面椭圆K3曲面上的半稳定对偶:构造了一类由跨壁现象联系起来的对偶的模空间,它可以用来描述秩为2的层的模空间与曲面上的Hilbert格式之间的双有理对应.在四维情况下,这可以用来得到模空间和弗里德曼描述的希尔伯特方案之间的同构。

英文摘要:

We study semistable pairs on elliptic K3 surfaces with a section: we construct a family of moduli spaces of pairs, related by wall crossing phenomena, which can be studied to describe the birational correspondence between moduli spaces of sheaves of rank 2 and Hilbert schemes on the surface. In the 4-dimensional case, this can be used to get the isomorphism between the moduli space and the Hilbert scheme described by Friedman.
