Measured asymptotic expanders and rigidity for Roe algebras
Kang Li, Ján Špakula, Jiawen Zhang
Our main result about rigidity of Roe algebras is the following: if and are metric spaces with bounded geometry such that their Roe algebras are -isomorphic, then an…
Higher Kazhdan projections, -Betti numbers and Baum-Connes conjectures
Kang Li, Piotr W. Nowak, Sanaz Pooya
We introduce higher-dimensional analogs of Kazhdan projections in matrix algebras over group -algebras and Roe algebras. These projections are constructed in the framework of…
The Haagerup property for twisted groupoid dynamical systems
Bartosz Kwaśniewski, Kang Li, Adam Skalski
We introduce the Haagerup property for twisted groupoid -dynamical systems in terms of naturally defined positive-definite operator-valued multipliers. By developing a version…
Strict comparison for -algebras arising from Almost finite groupoids
Pere Ara, Christian Bönicke, Joan Bosa +1
In this paper we show that for an almost finite minimal ample groupoid , its reduced -algebra has real rank zero and strict comparison even though $C_r^…
