论文摘要
在\ rcites {mafra：2019xms， *mafra：2019dddf，Brodelel：2019gba}中提出了两种不同的构造，产生了一环开放式弦振幅中出现的属属构型空间积分的低能扩展。我们将表明，这两种方法都可以追溯到Knizhnik-Zamolodchikov-Bernard（KZB）的椭圆系统，两次是圆环。我们为迭代积分的向量提供了一个具有额外标记的点的向量，并探索了两个代数发生器出现在两个微分方程中的代数。
Two different constructions generating the low-energy expansion of genus-one configuration-space integrals appearing in one-loop open-string amplitudes have been put forward in \rcites{Mafra:2019xms, *Mafra:2019ddf, Broedel:2019gba}. We are going to show that both approaches can be traced back to an elliptic system of Knizhnik--Zamolodchikov--Bernard(KZB) type on the twice-punctured torus. We derive an explicit all-multiplicity representation of the elliptic KZB system for a vector of iterated integrals with an extra marked point and explore compatibility conditions for the two sets of algebra generators appearing in the two differential equations.
