我们提供了一个第一性原理,微扰推导的AdS 5/CFT 4 Y-系统,已提出解决频谱问题的$ mathcal{N} = 4 $ SYM。该证明依赖于在一些回路算子的融合中的量子效应的计算,即转移矩阵。更准确地说,我们表明,领先的量子修正的融合的传输矩阵诱导正确的移动的光谱参数的T系统。作为中间步骤,我们研究了一阶线算子的UV发散,并计算了AdS 5 × S5中纯旋量弦的二阶线算子的融合。我们还认为,推导可以很容易地扩展到其他可积模型,其中一些描述弦理论的AdS 4,AdS 3和AdS 2时空。
We provide a first-principles, perturbative derivation of the AdS5/CFT4 Y-system that has been proposed to solve the spectrum problem of $ mathcal{N} = 4 $ SYM. The proof relies on the computation of quantum effects in the fusion of some loop operators, namely the transfer matrices. More precisely we show that the leading quantum corrections in the fusion of transfer matrices induce the correct shifts of the spectral parameter in the T-system. As intermediate steps we study UV divergences in line operators up to first order and compute the fusion of line operators up to second order for the pure spinor string in AdS5 × S5. We also argue that the derivation can be easily extended to other integrable models, some of which describe string theory on AdS4, AdS3 and AdS2 spacetimes.
