曲线的向量丛的对称积与模空间

Symmetric products and moduli spaces of vector bundles of curves

Kyoung-Seog Lee, M. S. Narasimhan

摘要:

设$X$是亏格为$g \geq 2$的光滑射影曲线,$M$是$X$上秩为2的稳定向量丛的模空间,其行列式同构于固定奇数度线丛$L$ .关于模的研究已有很多,最近$M$上相干层的有界导出范畴引起了人们的广泛关注。证明了$X$的导出范畴可以嵌入到$M$的导出范畴中.本文证明了当$X$为非超椭圆且为$g \geq 16$时,$X$的第二对称积的导出范畴可以嵌入$M$的导出范畴中.

英文摘要:

Let $X$ be a smooth projective curve of genus $g \geq 2$ and $M$ be the moduli space of rank 2 stable vector bundles on $X$ whose determinants are isomorphic to a fixed odd degree line bundle $L$. There has been a lot of works studying the moduli and recently the bounded derived category of coherent sheaves on $M$ draws lots of attentions. It was proved that the derived category of $X$ can be embedded into the derived category of $M$ by the second named author and Fonarev-Kuznetsov. In this paper we prove that the derived category of the second symmetric product of $X$ can be embedded into derived category of $M$ when $X$ is non-hyperelliptic and $g \geq 16$.
