Dynamical comparison for local homeomorphisms
Shirly Geffen, Shanshan Hua, Julian Kranz
We prove dynamical comparison for Deaconu--Renault groupoids associated to minimal surjective non-injective local homeomorphisms of compact metrizable spaces with finite Lebesgue c…

Cartan subalgebras in self-similar graph -algebras
Dawn Archey, Anna Duwenig, Shanshan Hua +3
For a self-similar graph , we find a distinguished subgroupoid of the associated path groupoid -- the symmetric cycline subgroupoid $\mathcal{S}_{\text{…

K-stability of Z-stable C*-algebras
Shanshan Hua
We provide a shorter new proof of the fact that Z-stable C*-algebras are K1-surjective using the Rørdam-Winter picture of the Jiang-Su algebra Z. Consequently, we recapture the K-…
