加权Coxeter图与Coxeter群的广义几何表示

Weighted Coxeter graphs and generalized geometric representations of Coxeter Groups

Vadim Bugaenko, Yonah Cherniavsky, Tatiana Nagnibeda, Robert Shwartz

摘要:

我们引入加权Coxeter图的概念,并将其与Coxeter群的标准几何表示的某种推广相关联。我们证明了这种表示的忠实性和不忠实性的充分条件。在加权Coxeter图是平衡的情况下,我们讨论了广义几何表示如何与Coxeter图上的数字游戏有关。

英文摘要:

We introduce the notion of weighted Coxeter graph and associate to it a certain generalization of the standard geometric representation of a Coxeter group. We prove sufficient conditions for faithfulness and non-faithfulness of such a representation. In the case when the weighted Coxeter graph is balanced we discuss how the generalized geometric representation is related to the numbers game played on the Coxeter graph.
