B-型Coxeter群的基定理的推广

Generalization of the basis theorem for the B-type Coxeter groups

Sawsan Khaskeia, Robert Shwartz

摘要:

非阿贝尔群的OGS是有限阿贝尔群的基的有趣推广。OGS的定义指出,群的每个元素都有一个唯一的表示,作为群的特定生成元的某些幂的乘积,以特定的给定顺序。对于对称群Sn,有R的纸. Shwartz,它证明了OGS和对称群的标准Coxeter表示之间的强联系,这被称为Sn的标准OGS。本文将Sn的标准OGS推广到有限经典Coxeter群Bn.我们描述了Bn的广义标准OGS的交换律,并将其与Bn的Coxeter长度和下降集联系起来。

英文摘要:

The OGS for non-abelian groups is an interesting generalization of the basis of finite abelian groups. The definition of OGS states that every element of a group has a unique presentation as a product of some powers of specific generators of the group, in a specific given order. In case of the symmetric groups Sn there is a paper of R. Shwartz, which demonstrates a strong connection between the OGS and the standard Coxeter presentation of the symmetric group, which is called the standard OGS of Sn. In this paper we generalize the standard OGS of Sn to the finite classical Coxeter group Bn. We describe the exchange laws for the generalized standard OGS of Bn, and we connect it to the Coxeter length and the descent set of Bn.
