Dimensions associated with surjective local homeomorphisms and subshifts with low complexity

Zhuofeng He, Sihan Wei

We prove that the Cuntz-Pimsner algebra associated to any surjective aperiodic one-sided subshift with finitely many left special elements has finite nuclear dimension, which is es…

A generalization of topological Rokhlin dimension and an embedding result

Sihan Wei, Zhuofeng He

We generalize Gabor's notion of topological Rokhlin dimension of -actions on compact metric space to a class of general discrete countable amenable group actions whic…

A note on crossed products of rotation algebras

Christian Bönicke, Sayan Chakraborty, Zhuofeng He +1

We compute the -theory of crossed products of rotation algebras , for any real angle , by matrices in with infinite order. Using te…

Isomorphism and Morita equivalence classes for crossed products of irrational rotation algebras by cyclic subgroups of

Christian Bönicke, Sayan Chakraborty, Zhuofeng He +1

Let be irrational numbers and be matrices in of infinite order. We compute the -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 and a finitely generated abelian group , we apply…
