特殊Brauer群与扭曲Picard簇

The special Brauer group and twisted Picard varieties

Daniel Huybrechts, Dominique Mattei

AI总结:

本文通过引入Grothendieck的特殊Brauer群,将带截面椭圆K3曲面的Tate-Shafarevich群概念推广至赋予线性系统的K3曲面,为处理扭曲层模空间提供了有效方法。

摘要:

我们将带截面椭圆K3曲面的Tate-Shafarevich群概念推广到赋予线性系统的K3曲面的Tate-Shafarevich群。该构造使用Grothendieck的特殊Brauer群,为处理K3曲面中曲线上支撑的扭曲层模空间提供了有效方法。

英文摘要:

We generalise the notion of the Tate-Shafarevich group of an elliptic K3 surface with a section to the Tate-Shafarevich group of a K3 surface endowed with a linear system. The construction, which uses Grothendieck's special Brauer group, provides an efficient way to deal with moduli spaces of twisted sheaves supported on curves in a K3 surface.
