| Aug 22, 2015 at 11:08 | comment | added | Edgar Ndie | yes I did. In that article, Brunner & Sidki want to prove that $GL_n(\mathbb{Z})$ is an automaton group. But I think it's not the case. Anyway I don't see any link with the fact that $BS(n,n)$ is an automaton group, $F_{|n|}\rtimes\mathbb{Z},$ and the fact $GL_n(\mathbb{Z})$ is an automaton group. The only link (which is false) I see is even if $BS(n,n)$ is a subgroup of $GL_n(\mathbb{Z})$ and $GL_n(\mathbb{Z})$ is an automaton group, it does not make $BS(n,n)$ an automaton group. | |
