Identities based on monodromy for integrations in string theory are used to derive relations between different color-ordered tree-level amplitudes in both bosonic and supersymmetric string theory. These relations imply that the color-ordered tree-level n-point gauge theory amplitudes can be expanded in a minimal basis of (n-3)! amplitudes. This result holds for any choice of polarizations of the external states and in any number of dimensions.
基于弦论中单值化的身份，用于推导出玻色子和超弦理论中不同颜色有序树级振幅之间的关系。这些关系意味着颜色有序树级 n 点规范理论振幅可以在(n-3)!个振幅的最小基中展开。该结果适用于外部状态的任何极化选择和任何维数。
