Classification of quasi-free compact group actions on Cuntz algebras

James Gabe

Quasi-free actions of finite groups on Cuntz algebras $O_{n}$ for $n \geq 2$ 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 $q A$ to Kasparov's $K K$ -theory, so as to cover versions of $K K$ such as $K K^{n u c}$ , $K K^{G}$ and ideal relate…
