Brin高维Thompson群$nV$的置换表示

Permutation-based presentations for Brin's higher-dimensional Thompson groups $nV$

Martyn Quick

摘要:

高维汤普森群$nV$($n \geq 2$)由布林在2005年引入。我们为这些无限单群中的每一个都提供了新的表示。第一种是无限表示,类似于有限对称群的Coxeter表示,生成集等于$nV$中的转置集,并反映了$n$维Cantor空间的自相似结构。然后,我们利用这个无限的介绍,以产生进一步的有限介绍,是相当小于那些以前已知的。

英文摘要:

The higher-dimensional Thompson groups $nV$, for $n \geq 2$, were introduced by Brin in 2005. We provide new presentations for each of these infinite simple groups. The first is an infinite presentation, analogous to the Coxeter presentation for the finite symmetric group, with generating set equal to the set of transpositions in $nV$ and reflecting the self-similar structure of $n$-dimensional Cantor space. We then exploit this infinite presentation to produce further finite presentations that are considerably smaller than those previously known.
