论文摘要
配备膨胀内态性的涂鸦组等于单方面的群体转移。我们表明这些群体的结构非常有限。更确切地说,我们表明,任何此类群体都可以分解为有限的单方面偏移和两个有限组的有限顺序。
A profinite group equipped with an expansive endomorphism is equivalent to a one-sided group shift. We show that these groups have a very restricted structure. More precisely, we show that any such group can be decomposed into a finite sequence of full one-sided group shifts and two finite groups.
