We attach to each finite bipartite separated graph (E,C) a partial dynamical system (Ω(E,C),F,θ), where Ω(E,C) is a zero-dimensional metrizable compact space, F is a finitely generated free group, and θ is a continuous partial action of F on Ω(E,C). The full crossed product C ⁎ -algebra O(E,C)=C(Ω(E,C))⋊θ⁎F is shown to be a canonical quotient of the graph C ⁎ -algebra C⁎(E,C) of the...
Necessary and sufficient conditions for when every non-zero ideal in a relative Cuntz–Pimsner ring contains a non-zero graded ideal, when a relative Cuntz–Pimsner ring is simple, and when every ideal in a relative Cuntz–Pimsner ring is graded, are given. A “Cuntz–Krieger uniqueness theorem” for relative Cuntz–Pimsner rings is also given and condition (L) and condition (K) for relative Cuntz–Pimsner...
