A note on the moduli spaces of holomorphic and logarithmic connections over a compact Riemann surface

Anoop Singh

摘要:

设$X$是亏格为$g \geq 3$的紧致黎曼曲面.本文研究了$X$上全纯联络的模空间和$X$上具有固定剩余的有限子集上奇异对数联络的模空间。我们确定了这些模空间的Chow群。计算了这些模空间上微分算子层的整体瓣及其对称幂,并证明了在一定条件下它们是常数。我们证明了对数联络的模空间的Torelli型定理。我们还描述了这些模空间的有理连通性。

英文摘要:

Let $X$ be a compact Riemann surface of genus $g \geq 3$. We consider the moduli space of holomorphic connections over $X$ and the moduli space of logarithmic connections singular over a finite subset of $X$ with fixed residues. We determine the Chow group of these moduli spaces. We compute the global sections of the sheaves of differential operators on ample line bundles and their symmetric powers over these moduli spaces, and show that they are constant under certain condition. We show the Torelli type theorem for the moduli space of logarithmic connections. We also describe the rational connectedness of these moduli spaces.
