非单缀规范群Vafa-Witten理论中的$S$ -对偶

$S$-duality in Vafa-Witten theory for non-simply laced gauge groups

Siye Wu

摘要:

Vafa-Witten理论是一个扭曲的N=4超对称规范理论,其配分函数是瞬子模空间的欧拉数的母函数。本文回顾了具有离散电通量和磁通量的量子规范理论,并回顾了规范群简单束缚时Vafa-Witten理论的主要结果。基于θ函数的变换及其在Blow-up公式中的出现,我们给出了规范群为非单缀时Hecke群下配分函数的显式变换.我们提供各种证据和一致性检查。

英文摘要:

Vafa-Witten theory is a twisted N=4 supersymmetric gauge theory whose partition functions are the generating functions of the Euler number of instanton moduli spaces. In this paper, we recall quantum gauge theory with discrete electric and magnetic fluxes and review the main results of Vafa-Witten theory when the gauge group is simply laced. Based on the transformations of theta functions and their appearance in the blow-up formulae, we propose explicit transformations of the partition functions under the Hecke group when the gauge group is non-simply laced. We provide various evidences and consistency checks.
