摘要

We derive explicit closed formulas for the Kirillov-Kostant-Souriau (KKS) coaction maps of open path regularized holonomies of the Knizhnik-Zamolodchikov (KZ) equation, and the corresponding Poisson brackets for the Lie algebra \(\textrm{gl}(N, \mathbb {C})\) gl ( N , C ) . Our main technical tool is a certain projection of the generalized pentagon equation of Alekseev et al. Generalized Pentagon equation, arXiv:2402.19138 [math.QA] (2025).
