Cantor-Bendixson ranks of countable SFTs
Abstract
We show that the possible Cantor-Bendixson ranks of countable SFTs are exactly the finite ordinals and ordinals of the form λ + 3, where λ is a computable ordinal. This result was claimed by the author in his PhD dissertation, but the proof contains an error, which is fixed in this note.
