摘要
本文在嵌入圆盘或圆柱体的有向图的弧的非交换权重空间 \(\Sigma \)上构建了范登贝格意义上的双准泊松括号,从而产生了 G. Massuyeau 和 V. Turaev 的准泊松括号。马苏约(G. Massuyeau)和图拉耶夫(V. Turaev)关于基于表面的基本群的群代数(textbf{k}/pi _1(\Sigma,p))。这个括号在循环空间 \(\mathcal C_\natural \)上也诱导了一个非交换高尔曼泊松括号,这是一个无基循环的线性空间({\textbf{k}}\)。我们证明,边界测量之间的诱导双准泊松括号可以通过非交换 r 矩阵形式主义来描述。这就从概念上证明了奥文豪斯(Adv Math 373:107309, 2020)的结果,即拉克斯算子的幂的迹形成了一个无限集合的非交换哈密顿的内卷,与\(\mathcal C_\natural \)上的非交换戈德曼括号有关。
In this paper a double quasi Poisson bracket in the sense of Van den Bergh is constructed on the space of noncommutative weights of arcs of a directed graph embedded in a disk or cylinder \(\Sigma \), which gives rise to the quasi Poisson bracket of G. Massuyeau and V. Turaev on the group algebra \(\textbf{k}\pi _1(\Sigma ,p)\) of the fundamental group of a surface based at \(p\in \partial \Sigma \). This bracket also induces a noncommutative Goldman Poisson bracket on the cyclic space\(\mathcal C_\natural \), which is a \({\textbf{k}}\)-linear space of unbased loops. We show that the induced double quasi Poisson bracket between boundary measurements can be described via noncommutative r-matrix formalism. This gives a more conceptual proof of the result of Ovenhouse (Adv Math 373:107309, 2020) that traces of powers of Lax operator form an infinite collection of noncommutative Hamiltonians in involution with respect to noncommutative Goldman bracket on \(\mathcal C_\natural \).
