Gauge-invariant ideals in the C*-algebras of finitely aligned higher-rank graphs

Aidan Sims

We produce a complete descrption of the lattice of gauge-invariant ideals in $C^{*} (Λ)$ for a finitely aligned $k$ -graph $Λ$ . We provide a condition on $Λ$ under which every ideal is…

A dual graph construction for higher-rank graphs, and $K$ -theory for finite 2-graphs

Stephen Allen, David Pask, Aidan Sims

Given a $k$ -graph $Λ$ and an element $p$ of $\NN^k$, we define the dual $k$ -graph, $p Λ$ . We show that when $Λ$ is row-finite and has no sources, the $C^{*}$ -algebras $C^{*} (Λ)$ and $C^…

Relative Cuntz-Krieger algebras of finitely aligned higher-rank graphs

Aidan Sims

We define the relative Cuntz-Krieger algebras associated to finitely aligned higher-rank graphs. We prove versions of the gauge-invariant uniqueness theorem and the Cuntz-Krieger u…

Higher-rank graphs and their C*-algebras

Iain Raeburn, Aidan Sims, Trent Yeend

We consider the higher-rank graphs introduced by Kumjian and Pask as models for higher-rank Cuntz-Krieger algebras. We describe a variant of the Cuntz-Krieger relations which appli…

SATEN: An Object-Oriented Web-Based Revision and Extraction Engine

Mary-Anne Williams, Aidan Sims

SATEN is an object-oriented web-based extraction and belief revision engine. It runs on any computer via a Java 1.1 enabled browser such as Netscape 4. SATEN performs belief revisi…
