Abstract
Given a one-sided subshift on a finite alphabet, we consider the semigroup , where is the language of , equipped with the multiplication operation given by concatenation, when allowed, and set to vanish otherwise. We then study the inverse hull , relating it with C*-algebras that have been discussed in the literature in association with subshifts.
