C*-algebras of commuting endomorphisms
Valentin Deaconu
Given a compact space X and two commuting continuous open surjective maps sigma_1, sigma_2 : X --> X, we construct certain C*-algebras that reflect the dynamics of the N^2-action.…
C*-algebras associated with interval maps
Valentin Deaconu, Fred Shultz
For each piecewise monotonic map tau of [0,1], we associate a pair of C*-algebras F_tau and O_tau and calculate their K-groups. The algebra F_tau is an AI-algebra. We characterize…
C*-algebras associated with branched coverings
Valentin Deaconu, Paul S. Muhly
In this note we analyze the C*-algebra associated with a branched covering both as a groupoid C*-algebra and as a Cuntz-Pimsner algebra. We determine conditions when the algebra is…
Cohomology of topological graphs and Cuntz-Pimsner algebras
V. Deaconu, A. Kumjian, P. Muhly
We compute the sheaf cohomology of a groupoid built from a local homeomorphism of a locally compact space . In particular, we identify the twists over this groupoid, and its Bra…
