Naimark's Problem for graph C*-algebras and Leavitt path algebras

Kulumani M. Rangaswamy, Mark Tomforde

We describe how boundary paths in a graph can be used to construct irreducible representations of the associated graph C*-algebra and the associated Leavitt path algebra. We use th…

Recasting the Hazrat Conjecture: Relating Shift Equivalence to Graded Morita Equivalence

Gene Abrams, Efren Ruiz, Mark Tomforde

Let and be finite graphs with no sinks, and any field. We show that shift equivalence of the adjacency matrices and , together with an additional compatibili…

A Cuntz-Krieger Uniqueness Theorem for Cuntz-Pimsner Algebras

Menevşe Eryüzlü, Mark Tomforde

We introduce a property of C*-correspondences, which we call Condition (S), to serve as an analogue of Condition (L) of graphs. We use Condition (S) to prove a Cuntz-Krieger Unique…

Morita equivalence for graded rings

Gene Abrams, Efren Ruiz, Mark Tomforde

The classical Morita Theorem for rings established the equivalence of three statements, involving categorical equivalences, isomorphisms between corners of finite matrix rings, and…

Matricial Archimedean order unit spaces and quantum correlations

Roy Araiza, Travis Russell, Mark Tomforde

We introduce a matricial analogue of an Archimedean order unit space, which we call a -AOU space. We develop the category of -AOU spaces and -positive maps and exhibit fun…

A Universal Representation for Quantum Commuting Correlations

Roy Araiza, Travis Russell, Mark Tomforde

We explicitly construct an Archimedean order unit space whose state space is affinely isomorphic to the set of quantum commuting correlations. Our construction only requires fundam…
