作为Dotsenko-Fateev积分判别式的共形块

Conformal blocks as Dotsenko-Fateev Integral Discriminants

A. Mironov, A. Morozov, Sh. Shakirov

摘要:

正如[1]中所预期的,在[2-4]中详细阐述的,并在[5]中明确表示的,Dotsenko-Fateev积分判别式与共形块一致,从而为AGT猜想提供了一种优雅的方法,而无需参考Nekrasov函数的辅助主题。在该识别中,共形块的内部尺寸与轮廓的选择相关联:对应的矩阵模型的DV阶段的参数。在本文中,我们提供了进一步的证据支持这个身份的6参数家庭的4点球共形块,到3级和任意值的外部尺寸和中心荷。我们还将这一结果推广到多点球面函数,并对环面上的1点函数的类似描述进行了评论。

英文摘要:

As anticipated in [1], elaborated in [2-4], and explicitly formulated in [5], the Dotsenko-Fateev integral discriminant coincides with conformal blocks, thus providing an elegant approach to the AGT conjecture, without any reference to an auxiliary subject of Nekrasov functions. Internal dimensions of conformal blocks in this identification are associated with the choice of contours: parameters of the DV phase of the corresponding matrix models. In this paper we provide further evidence in support of this identity for the 6-parametric family of the 4-point spherical conformal blocks, up to level 3 and for arbitrary values of external dimensions and central charges. We also extend this result to multi-point spherical functions and comment on a similar description of the 1-point function on a torus.
