Parametrization by Horizontal Constraints in the Study of Algorithmic Properties of -Subshift of Finite Type
Solène J. Esnay, Mathieu Sablik
The non-emptiness, called the Domino Problem, and the characterization of the possible entropies of -subshifts of finite type are standard problems of symbolic dynami…
