Expansive dynamics on profinite groups

Research output: Contribution to journalArticlepeer-review


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
