On the inclusion $\cO_2 \subset \cQ_2$

Jacopo Bassi, Roberto Conti

The diadic $C^{*}$ -algebra $\cQ_2$ contains canonically a copy of the Cuntz algebra $\cO_2$. It is shown that the inclusion $\cO_2 \subset \cQ_2$ is $C^{*}$ -irreducible and rigid. It f…

On $C^{*}$ -algebras associated to actions of discrete subgroups of $S L (2, R)$ on the punctured plane

Jacopo Bassi

Dynamical conditions that guarantee stability for discrete transformation group $C^{*}$ -algebras are determined. The results are applied to the case of some discrete subgroups of $SL…

Remarks on some simple $C^{*}$ -algebras admitting a unique lower semicontinuous $2$ -quasitrace

Jacopo Bassi

Using different descriptions of the Cuntz semigroup and of the Pedersen ideal, it is shown that $σ$ -unital simple $C^{*}$ -algebras with almost unperforated Cuntz semigroup, a unique…
