Computable $K$ -theory for C*-algebras II: AF algebras

Christopher J. Eagle, Isaac Goldbring, Timothy H. McNicholl

We continue the study of the effective content of $K$ -theory for C*-algebras, with a focus on AF algebras. We show that from a c.e. presentation of an AF algebra it is possible to…

Non-computability of $K$ -theory for computably presented C*-algebras

Christopher J. Eagle, Isaac Goldbring, Timothy H. McNicholl +1

We give an example of a unital C*-algebra $A$ with a computable presentation and for which neither $K_{0} (A)$ nor $K_{1} (A)$ has a computable presentation.
