Tilings of the hyperbolic plane of substitutive origin as subshifts of finite type on Baumslag-Solitar groups BS(1,n)

by   Nathalie Aubrun, et al.

We present a technique to lift some tilings of the discrete hyperbolic plane – tilings defined by a 1D substitution – into a zero entropy subshift of finite type (SFT) on non-abelian amenable Baumslag-Solitar groups BS(1,n) for n≥2. For well chosen hyperbolic tilings, this SFT is also aperiodic and minimal. As an application we construct a strongly aperiodic SFT on BS(1,n) with a hierarchical structure, which is an analogue of Robinson's construction on ℤ^2 or Goodman-Strauss's on ℍ_2.
