By Giuliano Boava and others

We associate a C*-algebra *\widetilde{\mathcal{O}}_{\textsf{X}}* with a subshift over an arbitrary, possibly infinite, alphabet. We show that *\widetilde{\mathcal{O}}_{\textsf{X}}* is a full invariant for topological conjugacy of the subshifts of Ott, Tomforde, and Willis. When the alphabet is countable, we show that *\widetilde{\mathcal{O}}_{\textsf{X}}* is an invariant for isometric conjugacy of subshifts... Show more
