AGT猜想与c=1时共形场论的可积结构

AGT conjecture and Integrable structure of Conformal field theory for c=1

A. Belavin, V. Belavin

摘要:

AGT对应给出了$d=2$共形场论的共形块的显式表达式。最近,通过代数$\mathcal{A}=Vir\otimes\mathcal{H}$模中存在特殊正交基的假设,在CFT框架内给出了这种表示的解释。基向量是无穷多个交换运动积分的特征向量。还证明其中一些向量采用杰克多项式的形式。本文猜想并通过显式计算证明了在Virasoro中心荷$c=1$的情形下,所有的基向量都是两个Jack多项式的乘积.每一个对易的运动积分都是两个无相互作用的卡洛杰罗模型的两个运动积分之和。我们还表明,在$c\neq1$的情况下,它是必要的,使用两个不同的Feigin-Fuks玻色化的维拉索罗代数的所有基向量的建设采取一个杰克多项式的形式。

英文摘要:

AGT correspondence gives an explicit expressions for the conformal blocks of $d=2$ conformal field theory. Recently an explanation of this representation inside the CFT framework was given through the assumption about the existence of the special orthogonal basis in the module of algebra $\mathcal{A}=Vir\otimes\mathcal{H}$. The basis vectors are the eigenvectors of the infinite set of commuting integrals of motion. It was also proven that some of these vectors take form of Jack polynomials. In this note we conjecture and verify by explicit computations that in the case of the Virasoro central charge $c=1$ all basis vectors are just the products of two Jack polynomials. Each of the commuting integrals of motion becomes the sum of two integrals of motion of two noninteracting Calogero models. We also show that in the case $c\neq1$ it is necessary to use two different Feigin-Fuks bosonizations of the Virasoro algebra for the construction of all basis vectors which take form of one Jack polynomial.
