On a family of -subalgebras of Cuntz-Krieger algebras
arXiv:2101.02317
Abstract
In this paper, we study a family of -subalgebras defined by fixed points of generalized gauge actions of a Cuntz-Krieger algebra, by introducing a family of étale groupoids whose associated -algebras are these -subalgebras. We know that topological conjugacy classes of one-sided topological Markov shifts are characterized in terms of the isomorphism classes of these étale groupoids.
