Crossed products and twisted -graph algebras
Nathan Brownlowe, Valentin Deaconu, Alex Kumjian +1
An automorphism of a -graph induces a crossed product which is isomorphic to a -graph algebra . In this…
Two families of Exel-Larsen crossed products
Nathan Brownlowe, Iain Raeburn
Larsen has recently extended Exel's construction of crossed products from single endomorphisms to abelian semigroups of endomorphisms, and here we study two families of her crossed…
Boundary quotients of the Toeplitz algebra of the affine semigroup over the natural numbers
Nathan Brownlowe, Astrid an Huef, Marcelo Laca +1
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…
