Riemann surface上平坦$SO(2n+1)$ -联络模空间的上同调环中的关系

Relations in the cohomology ring of the moduli space of flat $SO(2n+1)$-connections on a Riemann surface

Elisheva Adina Gamse, Jonathan Weitsman

摘要:

我们考虑黎曼曲面上平坦的$SO(2n+1)$ -联络(直到规范变换)的模空间,在一个标记点周围具有固定的完整性。在这个模空间上有自然的线丛,我们构造了这些线丛的陈省身类的几何代表,并证明了这些陈省身类生成的环在模空间的维数以下为零,推广了Newstead的一个猜想。

英文摘要:

We consider the moduli space of flat $SO(2n+1)$-connections (up to gauge transformations) on a Riemann surface, with fixed holonomy around a marked point. There are natural line bundles over this moduli space; we construct geometric representatives for the Chern classes of these line bundles, and prove that the ring generated by these Chern classes vanishes below the dimension of the moduli space, generalising a conjecture of Newstead.
