基于箭图理论和Seiberg对偶的局部阻塞曲线中的BPS态计数

BPS State Counting in Local Obstructed Curves from Quiver Theory and Seiberg Duality

Wu-yen Chuang, Guang Pan

摘要:

本文研究了法丛为O+O(-2)的局部阻塞曲线几何中的BPS态计数。我们发现BPS态有一个框架描述。使用这种描述与Seiberg对偶和本地化技术,我们可以计算BPS状态指数在不同的房间所规定的稳定性参数分配。这提供了一个定义良好的方法来计算广义Donaldson-Thomas不变量。该方法可推广到其它仿射ADE系统。

英文摘要:

In this paper we study the BPS state counting in the geometry of local obstructed curve with normal bundle O+O(-2). We find that the BPS states have a framed quiver description. Using this quiver description along with the Seiberg duality and the localization techniques, we can compute the BPS state indices in different chambers dictated by stability parameter assignments. This provides a well-defined method to compute the generalized Donaldson-Thomas invariants. This method can be generalized to other affine ADE quiver theories.
