Classification of graph C*-algebras with no more than four primitive ideals
Søren Eilers, Gunnar Restorff, Efren Ruiz
We describe the status quo of the classification problem of graph C*-algebras with four primitive ideals or less.
Ideal related K-theory with coefficients
Søren Eilers, Gunnar Restorff, Efren Ruiz
In this paper, we define an invariant, which we believe should be the substitute for total K-theory in the case when there is one distinguished ideal. Moreover, some diagrams relat…
Pictures of KK-theory for real C*-algebras and almost commuting matrices
Jeffrey L. Boersema, Terry A. Loring, Efren Ruiz
We give a systematic account of the various pictures of KK-theory for real C*-algebras, proving natural isomorphisms between the groups that arise from each picture. As part of thi…
Ideal-related K-theory for Leavitt path algebras and graph C*-algebras
Efren Ruiz, Mark Tomforde
We introduce a notion of ideal-related K-theory for rings, and use it to prove that if two complex Leavitt path algebras are Morita equivalent (respectively, isomorphic), then the…
Ideals in Graph Algebras
Efren Ruiz, Mark Tomforde
We show that the graph construction used to prove that a gauge-invariant ideal of a graph C*-algebra is isomorphic to a graph C*-algebra, and also used to prove that a graded ideal…
