We study the Toeplitz algebra $\TT(\N\rtimes\N^\times)$ and three quotients of this algebra: the -algebra $\qn$ recntly introduced by Cuntz, and two new ones, which we call th…

Co-universal C*-algebras associated to generalised graphs
Nathan Brownlowe, Aidan Sims, Sean T. Vittadello
We introduce P-graphs, which are generalisations of directed graphs in which paths have a degree in a semigroup P rather than a length in N. We focus on semigroups P arising as par…
