Constructions with Countable Subshifts of Finite Type
Ville Salo, Ilkka Törmä · Fundamenta Informaticae · 2013
We present constructions of countable two-dimensional subshifts of finite type (SFTs) with interesting properties. Our main focus is on properties of the topological derivatives and subpattern posets of these objects. We present a countable SFT whose
