Aperiodic subshifts of finite type on groups which are not finitely generated (2204.02447v3)
Published 5 Apr 2022 in math.DS and math.GR
Abstract: We provide an example of a non-finitely generated group which admits a nonempty strongly aperiodic SFT. Furthermore, we completely characterize the groups with this property in terms of their finitely generated subgroups and the roots of their conjugacy classes.
