一些可解自动机群

Some solvable automaton groups

Laurent Bartholdi, Zoran Šunik

摘要:

它表明,有限秩的自由阿尔贝群的某些上升HNN扩展,以及各种点灯群,可以实现为自动机群,即,可以被赋予自相似结构。这包括可解的Baumslag-Solitar群BS(1,m),其中m不是+/-1。此外,还证明了对任意互素整数m,n ≥ 2,Baumslag-Solitar群BS(1,m)和BS(1,n)对可由一对对偶自动机实现.然后,使用的例子来说明施赖尔图,自动机和对偶自动机的组合之间的更一般的连接。

英文摘要:

It is shown that certain ascending HNN extensions of free abelian groups of finite rank, as well as various lamplighter groups, can be realized as automaton groups, i.e., can be given a self-similar structure. This includes the solvable Baumslag-Solitar groups BS(1,m), for m not +/-1. In addition, it is shown that, for any relatively prime integers m,n>=2, the pair of Baumslag-Solitar groups BS(1,m) and BS(1,n) can be realized by a pair of dual automata. The examples are then used to illustrate more general connections between Schreier graphs, composition of automata and dual automata.
