Abstract

We introduce the Cuntz-Thomsen picture of C\mathcal{C}-equivariant Kasparov theory, denoted KKC\mathrm{KK}^\mathcal{C}, for a unitary tensor category C\mathcal{C} with countably many isomorphism classes of simple objects. We use this description of KKC\mathrm{KK}^\mathcal{C} to prove the stable uniqueness theorem in this setting.
