射影平面上层的框架旗模空间的阻塞理论

Obstruction theory for moduli spaces of framed flags of sheaves on the projective plane

Rodrigo A. Von Flach, Marcos Jardim, Valeriano Lanza

摘要:

在前一篇论文中,前两位作者建立了射影平面上层的框架标志的模空间与某个层的稳定表示的模空间之间的同构。在本注记中,我们用[5,定理17]中的一个命题代替了一个较弱的命题,这个命题是关于无阻模空间中无阻点的存在性。我们还扩展了引用的文件中的一些结果,关于最大的稳定性室,其中提到的同构举行,并存在一个完美的障碍理论的模空间。

英文摘要:

In a previous paper, the first two named authors established an isomorphism between the moduli space of framed flags of sheaves on the projective plane and the moduli space of stable representations of a certain quiver. In the present note, we substitute one of the claims made, namely [5, Theorem 17], for a weaker claim regarding the existence of unobstructed points in the quiver moduli space. We also extend some of the results of the cited paper, concerning the maximal stability chamber within which the isomorphism mentioned holds, and the existence of a perfect obstruction theory for the quiver moduli space.
