Abstract

We associate to each Temperley-Lieb-Jones C*-tensor category T ⁣LJ(δ)\mathcal{T}\!\mathcal{L}\mathcal{J}(\delta) with parameter δ\delta in the discrete range {2cos(π/(k+2)):k=1,2,}{2}\{2\cos(\pi/(k+2))\,:\,k=1,2,\ldots\}\cup\{2\} a certain C*-algebra B\mathcal{B} of compact operators. We use the unitary braiding on T ⁣LJ(δ)\mathcal{T}\!\mathcal{L}\mathcal{J}(\delta) to equip the category ModB\mathrm{Mod}_{\mathcal{B}} of (right) Hilbert B\mathcal{B}-modules with the structure of a braided C*-tensor category. We show that T ⁣LJ(δ)\mathcal{T}\!\mathcal{L}\mathcal{J}(\delta) is equivalent, as a braided C*-tensor category, to the full subcategory ModBf\mathrm{Mod}_{\mathcal{B}}^f of ModB\mathrm{Mod}_{\mathcal{B}} whose objects are those modules which admit a finite orthonormal basis. Finally, we indicate how these considerations generalize to arbitrary finitely generated rigid braided C*-tensor categories.
