for -algebras

James Gabe, Alistair Miller

We introduce a topological abelian group for every -algebra , which is functorial in and invariant under stabilisations. $\mathrm{K}_1^Δ…

Classification of quasi-free compact group actions on Cuntz algebras

James Gabe

Quasi-free actions of finite groups on Cuntz algebras for are classified up to conjugacy by data in the representation ring. Partial results are obtained f…

Generalized homomorphisms and KK with extra structure

Joachim Cuntz, James Gabe

We develop the approach via quasihomomorphisms and the universal algebra to Kasparov's -theory, so as to cover versions of such as , and ideal relate…

Inclusions of real rank zero

James Gabe, Robert Neagu

We introduce a notion of real rank zero for inclusions of C-algebras. After showing that our definition has many equivalent characterisations, we offer a complete description o…

Tracially Complete C*-Algebras

José R. Carrión, Jorge Castillejos, Samuel Evington +4

We introduce a new class of operator algebras -- tracially complete C*-algebras -- as a vehicle for transferring ideas and results between C*-algebras and their tracial von Neumann…

Extensions of C*-algebras

James Gabe, Huaxin Lin, Ping Wong Ng

Let be a separable amenable -algebra and a non-unital and -unital simple -algebra with continuous scale ( need not be stable). We classify, up to unitary eq…
