Gaoli Chen, Robert de Mello Koch, Minkyoo Kim, Hendrik J. R. Van Zyl

摘要:

在${\cal N}=4$超Yang-Mills理论的背景下,近年来发展了一种计算行列式、子行列式、永久算子和迹的关联函数的有效方法.在这篇文章中,我们表明,它们可以扩展到ABJM和ABJ理论。利用一个新的恒等式,它遵循的特征正交性,某些投影算子用于定义Schur多项式的积分表示。该积分表示提供了感兴趣的关联函数的有效描述。由此产生的有效的描述有${1\over N}$作为循环计数参数,强烈表明其相关的全息。

英文摘要:

Efficient and powerful approaches to the computation of correlation functions involving determinant, sub-determinant and permanent operators, as well as traces, have recently been developed in the setting of ${\cal N}=4$ super Yang-Mills theory. In this article we show that they can be extended to ABJM and ABJ theory. After making use of a novel identity which follows from character orthogonality, an integral representation of certain projection operators used to define Schur polynomials is given. This integral representation provides an effective description of the correlation functions of interest. The resulting effective descriptions have ${1\over N}$ as the loop counting parameter, strongly suggesting their relevance for holography.
