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…
Purely infinite simple C*-algebras associated to integer dilation matrices
Ruy Exel, Astrid an Huef, Iain Raeburn
Given an n x n integer matrix A whose eigenvalues are strictly greater than 1 in absolute value, let σ_A be the transformation of the n-torus T^n=R^n/Z^n defined by σ_A(e^{2πix})=e…
Full and reduced coactions of locally compact groups on C*-algebras
Astrid an Huef, John Quigg, Iain Raeburn +1
We survey the results required to pass between full and reduced coactions of locally compact groups on C*-algebras, which say, roughly speaking, that one can always do so without c…
