Realizing finitely presented groups as projective fundamental groups of SFTs

Résumé

Subshifts are sets of colourings-or tilings-of the plane, defined by local constraints. Historically introduced as discretizations of continuous dynamical systems, they are also heavily related to computability theory. In this article, we study a conjugacy invariant for subshifts, known as the projective fundamental group and we show that any finitely presented group can be realized as a projective fundamental group of some SFT.
