$k$ -graph algebras are iterated Cuntz-Pimsner algebras -- from the bottom up

Valentin Deaconu, MenevÅe EryÃ¼zlÃ¼ Paulovicks, S. Kaliszewski +1

We introduce a new method of expressing a $k$ -graph $C^{*}$ -algebra as a Cuntz-Pimsner algebra. Kumjian, Pask, and Sims have done this directly, using a linking algebra approach and…

Comparing Two Notions of Coaction Invariance of Ideals in $C^{*}$ -Algebras

Matthew Gillespie, Benjamin Jones, S. Kaliszewski +1

Given a coaction $I^´$ of a locally compact group $G$ on a $C^{*}$ -algebra $A$ , we study the relationship between two different forms of coaction invariance of ideals of $A$ …

S. Kaliszewski, John Quigg, Dana P. Williams

We use the Ladder Technique to establish bijections between the ideals of related Fell bundles.
