A note on crossed products of rotation algebras

Christian Bönicke, Sayan Chakraborty, Zhuofeng He +1

We compute the $K$ -theory of crossed products of rotation algebras $A_{θ}$ , for any real angle $θ$ , by matrices in $SL (2, Z)$ with infinite order. Using te…

Isomorphism and Morita equivalence classes for crossed products of irrational rotation algebras by cyclic subgroups of $S L_{2} (Z)$

Christian Bönicke, Sayan Chakraborty, Zhuofeng He +1

Let $θ, θ^{'}$ be irrational numbers and $A, B$ be matrices in $S L_{2} (Z)$ of infinite order. We compute the $K$ -theory of the crossed product $\mathcal{A}_θ\rtimes_A \mathbb{Z…

Certain actions of finitely generated groups on higher dimensional noncommutative tori

Zhuofeng He

We study certain actions of finitely generated abelian groups on higher dimensional noncommutative tori. Given a dimension $d$ and a finitely generated abelian group $G$ , we apply…
