簇代数的Artin群表示

Artin Group Presentations Arising from Cluster Algebras

Jacob Haley, David Hemminger, Aaron Landesman, Hailee Peck

摘要:

2003年,Fomin和Zelevinsky证明了有限型簇代数可以用Dynkin图进行分类。然后在2013年,Barot和Marsh定义了与Dynkin图相关的反射群的表示,即边加权的定向图,并证明了这个群在图突变下是不变的(直到同构)。在本文中,我们扩展Barot和马什的结果,阿廷组介绍,定义新的发电机关系,并显示这些演示的突变不变性。

英文摘要:

In 2003, Fomin and Zelevinsky proved that finite type cluster algebras can be classified by Dynkin diagrams. Then in 2013, Barot and Marsh defined the presentation of a reflection group associated to a Dynkin diagram in terms of an edge-weighted, oriented graph, and proved that this group is invariant (up to isomorphism) under diagram mutations. In this paper, we extend Barot and Marsh's results to Artin group presentations, defining new generator relations and showing mutation-invariance for these presentations.
