K-theoretic invariants of four three-dimensional operator systems
Abstract
We compute K-theoretic invariants for four three-dimensional operator systems to illustrate the general theory. We find that in some cases the invariants distinguish the operator system from its C*-envelope, while in others they do not. We also explore extensions of the theory.
