A geometric obstruction to self-simulation for groups
Sebastián Barbieri, Kanéda Blot, Mathieu Sablik +1
We introduce a new quasi-isometry invariant for finitely generated groups and show that every group with this property admits a subshift which is effectively closed by patterns and…
Minimal sofic shift on a group that is not finitely-generated
Ville Salo
We prove that there exists a group which is not finitely generated, but admits a minimal sofic shift. This answers a question of Doucha, Melleray and Tsankov. The group is of the f…
Finitary Ryan's and local entropy for subshifts
Ville Salo, Scott Schmieding
For the action of a group by homeomorphisms on a space , the automorphism group consists of all self-homeomorphisms of which commute with $x \mapsto…
Soficity of free extensions of effective subshifts
Sebastián Barbieri, Mathieu Sablik, Ville Salo
Let be a group and a subgroup. The free extension of an -subshift to is the -subshift whose configurations are those for which the…
