摘要

簇交换群（Cluster Exchange Groupoids）是邱锴为研究稳定性条件和二次微分而引入的簇交换图的增强。在本文中，我们引入了任意有限 Coxeter-Dynkin 图 Δ 的簇交换群，并证明其基本群与与 Δ 相关的相应辫状群同构。

Cluster braid groups of Coxeter-Dynkin diagrams

Cluster exchange groupoids are introduced by King-Qiu as an enhancement of cluster exchange graphs to study stability conditions and quadratic differentials. In this paper, we introduce the cluster exchange groupoid for any finite Coxeter-Dynkin diagram Δ and show that its fundamental group is isomorphic to the corresponding braid group associated with Δ.
