阿贝尔簇上$Λ$ -模的模空间

Moduli spaces of $Λ$-modules on abelian varieties

Emilio Franco, Pietro Tortella

摘要:

研究了交换簇$X$上消失陈类的半稳定$Λ$ -模的模空间$\mathbf{M}_X(Λ, n)$,其中$Λ$属于$D$ -代数的某个子类.特别地,对于$Λ= \mathcal{D}_X$(分别为$Λ= \mathrm{Sym}^\bullet \mathcal{T}X$)得到了平坦联络的模空间的一个刻画(分别为. Higgs bundles)。我们用对偶阿贝尔簇$\hat{X}$上的某个纤维丛的对称积来刻划$\mathbf{M}_X(Λ, n)$.我们也给出了模解释相关的希尔伯特方案作为分类空间的$Λ$ -模的额外结构。最后,我们研究了与这些新的模空间相关的非交换Hodge理论。

英文摘要:

We study the moduli space $\mathbf{M}_X(Λ, n)$ of semistable $Λ$-modules of vanishing Chern classes over an abelian variety $X$, where $Λ$ belongs to a certain subclass of $D$-algebras. In particular, for $Λ= \mathcal{D}_X$ (resp. $Λ= \mathrm{Sym}^\bullet \mathcal{T}X$) we obtain a description of the moduli spaces of flat connections (resp. Higgs bundles). We give a description of $\mathbf{M}_X(Λ, n)$ in terms of a symmetric product of a certain fibre bundle over the dual abelian variety $\hat{X}$. We also give a moduli interpretation to the associated Hilbert scheme as the classifying space of $Λ$-modules with extra structure. Finally, we study the non-abelian Hodge theory associated to these new moduli spaces.
