麦克唐纳指数作为手征代数精化特征的检验

Testing Macdonald Index as a Refined Character of Chiral Algebra

Akimi Watanabe, Rui-Dong Zhu

摘要:

我们在$(A_{n-1},A_{m-1})$ Argyres-Douglas理论中用$\mathrm{gcd}(n,m)=1$检验了宋在arXiv:1612.08956中提出的Macdonald指数给出了对偶手征代数的一个精细特征。特别地,我们通过TQFT图像和Gaiotto-Rastelli-Razamat的Higgsing方法,将分析扩展到更高秩的理论和Macdonald指数与表面算子。在大$m$极限下,利用对偶$(A_{n-1},A_{m-1})$理论建立了高阶极小模型的精化特征标的处方,从而为Song提出的在有限$m$下(至少)在某些简单模(包括真空模)中成立的观点提供了证据.我们还讨论了我们的方法中观察到的一些不匹配。

英文摘要:

We test in $(A_{n-1},A_{m-1})$ Argyres-Douglas theories with $\mathrm{gcd}(n,m)=1$ the proposal of Song's in arXiv:1612.08956 that the Macdonald index gives a refined character of the dual chiral algebra. In particular, we extend the analysis to higher rank theories and Macdonald indices with surface operator, via the TQFT picture and Gaiotto-Rastelli-Razamat's Higgsing method. We establish the prescription for refined characters in higher rank minimal models from the dual $(A_{n-1},A_{m-1})$ theories in the large $m$ limit, and then provide evidence for Song's proposal to hold (at least) in some simple modules (including the vacuum module) at finite $m$. We also discuss some observed mismatch in our approach.
