曲线上PGL(r)-丛模空间的Brauer群

Brauer Group of Moduli Spaces of PGL(r)-Bundles over a curve

Indranil Biswas, Amit Hogadi

摘要:

我们计算了特征为零的代数闭域上曲线$X$上稳定PGL(r)-丛的模堆叠的Brauer群.我们还证明了这种模堆叠的Brauer群与$X$上稳定PGL(r)-丛的相应粗模空间的光滑轨迹的Brauer群重合。

英文摘要:

We compute the Brauer group of the moduli stack of stable PGL(r)-bundles on a curve $X$ over an algebraically closed field of characteristic zero. We also show that the Brauer group of such a moduli stack coincides with the Brauer group of the smooth locus of the corresponding coarse moduli space of stable PGL(r)-bundles on $X$.
