多年前，在无质量RG流的框架中，人们注意到由能量-动量张量的分量构成的无关复合算子在二维量子场论中具有非常特殊的性质，可以看作是一种特殊的可积微扰。近年来，在对有效弦理论模型的研究中出现了一些新的有趣的算子特征。
It was noticed many years ago, in the framework of massless RG flows, that the irrelevant composite operator, built with the components of the energy-momentum tensor, enjoys very special properties in 2D quantum field theories, and can be regarded as a peculiar kind of integrable perturbation. Novel interesting features of this operator have recently emerged from the study of effective string theory models.
