The nuclear dimension of graph C*-algebras
Efren Ruiz, Aidan Sims, Mark Tomforde
Consider a graph C*-algebra C*(E) with a purely infinite ideal I (possibly all of C*(E)) such that I has only finitely many ideals and C*(E)/I is approximately finite dimensional.…
Classification of tight -algebras over the one-point compactification of
James Gabe, Efren Ruiz
We prove a strong classification result for a certain class of -algebras with primitive ideal space , where is the one-point…
Automorphisms of Cuntz-Krieger algebras
Søren Eilers, Gunnar Restorff, Efren Ruiz
We prove that the natural homomorphism from Kirchberg's ideal-related KK-theory, KKE(e, e'), with one specified ideal, into Hom_Λ (\underline{K}_{E} (e), \underline{K}_{E} (e')) is…
Identifying AF-algebras that are graph C*-algebras
Soren Eilers, Takeshi Katsura, Efren Ruiz +1
We consider the problem of identifying exactly which AF-algebras are isomorphic to a graph C*-algebra. We prove that any separable, unital, Type I C*-algebra with finitely many ide…
Strong classification of extensions of classifiable C*-algebras
Soren Eilers, Gunnar Restorff, Efren Ruiz
We show that certain extensions of classifiable C*-algebra are strongly classified by the associated six-term exact sequence in K-theory together with the positive cone of K_{0}-gr…
