Bockstein operations and AD algebras with unbounded torsion in
Qingnan An, Zhichao Liu, Xin Ma
Eilers showed that for AD algebras of real rank zero with bounded torsion in , the coefficient transformations are redundant in the classification by ordered scal…
Subhomogeneity in the classification of real rank zero C*-algebras
Qingnan An, Søren Eilers, Guihua Gong +1
In this paper, we construct a class of ASH algebras of real rank zero and stable rank one which is not K-pure. Then we show the following: (i) There exists a real rank zero inducti…
Bockstein operations and extensions with trivial boundary maps
Qingnan An, Zhichao Liu
In this paper, we investigate the relationship between ideal structures and the Bockstein operations in the total K-theory, offering various diagrams to demonstrate their effective…
Classification of homomorphisms from to a -algebra
Qingnan An, George Elliott, Zhichao Liu
Let be a compact subset of and let be a unital simple, separable -algebra with stable rank one, real rank zero and strict comparison. We show that, given…
A latticed total K-theory
Qingnan An, Chunguang Li, Zhichao Liu
In this paper, a new invariant was built towards the classification of separable C*-algebras of real rank zero, which we call latticed total K-theory. A classification theorem is g…
