C*-envelopes for operator algebras with a coaction and co-universal C*-algebras for product systems
Adam Dor-On, Evgenios T. A. Kakariadis, Elias G. Katsoulis +2
A cosystem consists of a possibly nonselfadoint operator algebra equipped with a coaction by a discrete group. We introduce the concept of C*-envelope for a cosystem; roughly speak…

Applications of entropy of product systems: higher-rank graphs
Evgenios T. A. Kakariadis
We consider C*-algebras of finite higher-rank graphs along with their rotational action. We show how the entropy theory of product systems with finite frames applies to identify th…
