T^2 × S^2上的超对称指数与椭圆亏格

Supersymmetric index on T^2 x S^2 and elliptic genus

Masazumi Honda, Yutaka Yoshida

摘要:

研究了四维$\mathcal{N}=1$超对称场论在$T^2 \times S^2$上的配分函数。利用超对称局域化方法,证明了$T^2 \times S^2$配分函数是由二维$\mathcal{N}=(0,2)$理论的椭圆亏格给出的。作为应用,我们讨论了Gadde,Gukov和Putrov提出的4d Seiberg对偶与2d $(0,2)$ trial之间的关系.在其他例子中,我们确定4d理论给出椭圆属的K3,M-字符串和E-字符串。在K3的例子中,我们发现有两个4d理论给出了K3的椭圆亏格。这将意味着新的四维二元性。

英文摘要:

We study partition function of four-dimensional $\mathcal{N}=1$ supersymmetric field theory on $T^2 \times S^2$. By applying supersymmetry localization, we show that the $T^2 \times S^2$ partition function is given by elliptic genus of certain two-dimensional $\mathcal{N}=(0,2)$ theory. As an application, we discuss a relation between 4d Seiberg duality duality and 2d $(0,2)$ triality, proposed by Gadde, Gukov and Putrov. In other examples, we identify 4d theories giving elliptic genera of K3, M-strings and E-strings. In the example of K3, we find that there are two 4d theories giving the elliptic genus of K3. This would imply new four-dimensional duality.
