Toda共形场论的概率构造

Probabilistic construction of Toda conformal field theories

Baptiste Cerclé, Rémi Rhodes, Vincent Vargas

摘要:

继1984年Belavin、Polyakov和Zamolodchikov在二维共形场论上的开创性工作之后,户田共形场论作为二维共形场论的一个家族被引入物理学文献中,除了共形对称性之外,它们还具有扩展的对称性,通常被称为W对称性或更高自旋对称性。更确切地说,户田共形场论提供了一种自然的方式,将有限维简单和复杂李代数与一种共形场论联系起来,这种场论的对称代数包含维拉索罗代数。在本文中,我们使用这些模型的路径积分公式提供了一个严格的数学结构户田共形场论的基础上概率论。通过这样做,我们恢复了预期的性质的理论,如Weyl异常公式相对于由共形因子和Seiberg界的关联函数的背景度量的变化。

英文摘要:

Following the 1984 seminal work of Belavin, Polyakov and Zamolodchikov on two-dimensional conformal field theories, Toda conformal field theories were introduced in the physics literature as a family of two-dimensional conformal field theories that enjoy, in addition to conformal symmetry, an extended level of symmetry usually referred to as W-symmetry or higher-spin symmetry. More precisely Toda conformal field theories provide a natural way to associate to a finite-dimensional simple and complex Lie algebra a conformal field theory for which the algebra of symmetry contains the Virasoro algebra. In this document we use the path integral formulation of these models to provide a rigorous mathematical construction of Toda conformal field theories based on probability theory. By doing so we recover expected properties of the theory such as the Weyl anomaly formula with respect to the change of background metric by a conformal factor and the existence of Seiberg bounds for the correlation functions.
