Complexity rank one implies real rank zero

Qingnan An, Zhichao Liu

We show that $C^{*}$ -algebras with complexity rank one have real rank zero, as an application, the uniform Roe algebra $C_{u}^{*} ∣ Z ∣$ has real rank zero.

Bockstein operations and AD algebras with unbounded torsion in $K_{1}$

Qingnan An, Zhichao Liu, Xin Ma

Eilers showed that for AD algebras of real rank zero with bounded torsion in $K_{1}$ , the coefficient transformations $κ$ are redundant in the classification by ordered scal…
