Coactions and Fell bundles

S. Kaliszewski, Paul S. Muhly, John Quigg +1

We show that if is a Fell bundle over a locally compact group , then there is a natural coaction of on the Fell-bundle -algebra such that if

Equivalence and Disintegration Theorems for Fell Bundles and their C*-algebras

Paul S. Muhly, Dana P. Williams

We study the C*-algebras of Fell bundles. In particular, we prove the analogue of Renault's disintegration theorem for groupoids. As in the groupoid case, this result is the key st…

Groupoid and Inverse Semigroup Presentations of Ultragraph -Algebras

Alberto Marrero, Paul S. Muhly

Inspired by the work of Paterson on -algebras of directed graphs, we show how to associate a groupoid to an ultragraph in such…

The Poisson Kernel for Hardy Algebras

Paul S. Muhly, Baruch Solel

This note contributes to a circle of ideas that we have been developing recently in which we view certain abstract operator algebras , which we call Hardy algebras,…

Higher-rank graph C*-algebras: an inverse semigroup and groupoid approach

Cynthia Farthing, Paul S. Muhly, Trent Yeend

We provide inverse semigroup and groupoid models for the Toeplitz and Cuntz-Krieger algebras of finitely aligned higher-rank graphs. Using these models, we prove a uniqueness theor…
