C*-Algebras of one-sided subshifts over arbitrary alphabets
Giuliano Boava, Gilles G. de Castro, Daniel Gonçalves +1
We associate a C*-algebra with a subshift over an arbitrary, possibly infinite, alphabet. We show that …
Infinite sum relations on universal C*-algebras
Giuliano Boava, Gilles G. de Castro
We extend the usual theory of universal C*-algebras from generators and relations in order to allow some relations to be described using the strong operator topology. In particular…
Groupoid models for the C*-algebra of labelled spaces
Giuliano Boava, Gilles G. de Castro, Fernando de L. Mortari
We define a groupoid from a labelled space and show that it is isomorphic to the tight groupoid arising from an inverse semigroup associated with the labelled space. We then define…
Partial crossed product description of the C*-algebras associated with integral domains
Giuliano Boava, Ruy Exel
Recently, Cuntz and Li introduced the C^*-algebra A[R] associated to an integral domain R with finite quotients. In this paper, we show that A[R] is a partial group algebra of the…
