Crossed products of operator algebras and the K-theory of Cuntz algebras on spaces
N. Christopher Phillips
For we define and study full and reduced crossed products of algebras of operators on -finite spaces by isometric actions of second countable locally…
Isomorphism, nonisomorphism, and amenability of L^p UHF algebras
N. Christopher Phillips
In a previous paper, we introduced L^p UHF algebras for p in [1, \infty). We concentrated on the spatial L^p UHF algebras, which are classified up to isometric isomorphism by p and…
Simplicity of UHF and Cuntz algebras on ~spaces
N. Christopher Phillips
We prove that, for and integers at least 2, the analog of the Cuntz algebra is a purely infinite simple amenabl…
The K-Theory of a Simple Separable Exact C*-Algebra Not Isomorphic to Its Opposite Algebra
N. Christopher Phillips, Maria Grazia Viola
We construct uncountably many mutually nonisomorphic simple separable stably finite unital exact C-algebras which are not isomorphic to their opposite algebras. In particula…
Crossed products by spectrally free actions
Cornel Pasnicu, N. Christopher Phillips
We define spectral freeness for actions of discrete groups on C*-algebras. We relate spectral freeness to other freeness conditions; an example result is that for an action of a fi…
