It is a well-known result by Hanany and Witten that, when two five-branes move across each other, D3-branes stretching between them are generated. Later the same brane configurations played a crucial role in understanding the worldvolume theory of multiple M2-branes. Recently the partition function of multiple M2-branes was transformed to the Fredholm determinant for quantum algebraic curves, where the characteristic 3/2 power law of degrees of freedom is reproduced and the determinant enjoys large symmetries given by exceptional Weyl groups. The large exceptional Weyl group reproduces the Hanany-Witten brane transitions and, besides, contains brane transitions unknown previously. Aiming at understanding the new brane transitions better, we generalize our previous study on the D5 quantum curve to the E7 case, which requires delicate handling of degeneracies. By combining the results of these two cases, we propose a “local” rule for the brane transitions.

来自特殊群的 Brane 过渡

Hanany 和 Witten 的一个众所周知的结果是,当两个五膜相互移动时,会产生在它们之间伸展的 D3 膜。后来相同的膜配置在理解多个 M2 膜的世界体积理论方面发挥了关键作用。最近,多个 M2-膜的配分函数被转换为量子代数曲线的 Fredholm 行列式,其中重现了自由度的特征 3/2 幂律,并且行列式享有由例外 Weyl 群给出的大对称性。大的特殊 Weyl 群再现了 Hanany-Witten 膜跃迁,此外,还包含以前未知的膜跃迁。为了更好地理解新的膜转变,我们概括了我们之前对D5 量子曲线 7情况,这需要对退化进行精细处理。通过结合这两种情况的结果,我们提出了膜转换的“局部”规则。
