拓扑弦的Toda三点函数

Toda 3-Point Functions From Topological Strings

Vladimir Mitev, Elli Pomoni

摘要:

我们认为长期存在的问题,获得户田CFT的3点功能。我们的主要工具是拓扑弦和规范理论与二维CFTs之间的AGT-W关系。在arXiv:1310.3841中,我们计算了$S^4 \times S^1$上的5D $T_N$理论的配分函数,并建议将它们解释为q变形Toda的三点结构常数。在本文中,我们提供了精确的AGT-W字典的这种关系和重写的5D $T_N$配分函数的形式,使采取的4D限制。因此,我们得到了一个处方的计算的配分函数的4D $T_N$理论上的$S^4$,或等效的未变形的3点Toda结构常数。我们的公式,有正确的对称性,零,它应该和,对于$N=2$,给出了已知的答案刘维CFT。

英文摘要:

We consider the long-standing problem of obtaining the 3-point functions of Toda CFT. Our main tools are topological strings and the AGT-W relation between gauge theories and 2D CFTs. In arXiv:1310.3841 we computed the partition function of 5D $T_N$ theories on $S^4 \times S^1$ and suggested that they should be interpreted as the three-point structure constants of q-deformed Toda. In this paper, we provide the exact AGT-W dictionary for this relation and rewrite the 5D $T_N$ partition function in a form that makes taking the 4D limit possible. Thus, we obtain a prescription for the computation of the partition function of the 4D $T_N$ theories on $S^4$, or equivalently the undeformed 3-point Toda structure constants. Our formula, has the correct symmetry properties, the zeros that it should and, for $N=2$, gives the known answer for Liouville CFT.
