In very rough terms, let $ A$ be a complex unital $ C^*$ -algebra. Assume it nuclear for convenience, but it doesn’t matter much. Consider the ‘Fock’-type $ C^*$ -algebra (don’t know a better name for it) $ $ \mathbb{C}\bigoplus A\bigoplus A\otimes A\bigoplus\ldots $ $ This can be thought of as the $ C^*$ -algebraRead more
