A general framework for quasi-isometries in symbolic dynamics beyond groups
Sebastián Barbieri, Nicolás Bitar
We introduce an algebraic structure which encodes a collection of countable graphs through a set of states, generators and relations. These structures, which we call blueprints, ca…

Realizability of Subgroups by Subshifts of Finite Type
Nicolás Bitar
We study the problem of realizing families of subgroups as the set of stabilizers of configurations from a subshift of finite type (SFT). This problem generalizes both the existenc…
