We consider two relatively natural topologizations of the set of all cellular automata on a fixed alphabet. The first turns out to be rather pathological, in that the countable spa…

On Derivatives and Subpattern Orders of Countable Subshifts
Ville Salo, Ilkka Törmä
We study the computational and structural aspects of countable two-dimensional SFTs and other subshifts. Our main focus is on the topological derivatives and subpattern posets of t…
