Non-stationarity of isomorphism between AF algebras defined by stationary Bratteli diagrams
Non-stationarity of isomorphism between AF algebras defined by stationary Bratteli diagrams
We first study situations where the stable AF algebras defined by two square primitive non-singular incidence matrices with non-negative integer matrix elements are isomorphic, even though no powers of the associated automorphisms of thecorresponding dimension groups are isomorphic. More generally we consider necessary and sufficient conditions for two such matrices …
