RT Journal Article T1 The reduction theorem for algebras of one-sided subshifts over arbitrary alphabets. A1 Bagio, Dirceu A1 Gil-Canto, Cristóbal A1 Gonçalves, Daniel A1 Royer, Danilo K1 Algebra lineal AB Let R be a commutative unital ring, X a subshift, and A_R(X) the corresponding unital subshift algebra. We establish the reduction theorem for A_R(X). As a consequence, we obtain a Cuntz-Krieger uniqueness theorem for A_R(X) and we show that A_R(X) is semiprimitive (resp. semiprime) whenever R is a field (resp. a domain).
