在本文中,我们展示了如何简化[4]中用于计算 (d + 1) 维 AdS 空间中的两点函数的方法。这产生了一种用于评估作为第二类勒让德函数的线性组合的两点函数的算法。该算法可以很容易地在计算机上实现。为了便于说明,我们显示了秩高达 l = 4 的对称无迹张量场情况的结果。
In this paper we show how the method of [4] for the calculation of two-point functions in (d + 1)-dimensional AdS space can be simplified. This results in an algorithm for the evaluation of the two-point functions as linear combinations of Legendre functions of the second kind. This algorithm can be easily implemented on a computer. For the sake of illustration, we displayed the results for the case of symmetric traceless tensor fields with rank up to l = 4.
