Abstract:
We construct an action of Zk on a compact zero-dimensional space obtained from a higher graph Λ satisfying a mild assumption generalizing the construction of the Markov shift associated to a nonnegative integer matrix. The stable Ruelle algebra Rs(Λ) is shown to be strongly Morita equivalent to C∗(Λ). Hence Rs(Λ) is simple, stable and purely infinite, if Λ satisfies the aperiodicity condition.
