Topology
The subshift of finite type has a natural topology, derived from the product topology on, where
and V is given the discrete topology.
A basis for the topology of the shift of finite type is the family of cylinder sets
The cylinder sets are clopen sets. Every open set in the subshift of finite type is a countable union of cylinder sets. In particular, the shift T is a homeomorphism; that is, with respect to this topology, it is continuous with continuous inverse.
