Web2-algebra (or a Hopf version) should be compared with the diﬃculty in deﬁning precisely the meaning of quantum groups (or quantum algebras). The analogy is actually expected to be meaningful: while quantization turns certain algebras into quantum algebras, “categoriﬁca-tion” should turn those algebras into 2-algebras. WebG. As in the Kac algebra case, we use order properties of A∗∗ to determine L1(G) inside A∗. Our characterisation of such isometric isomorphisms involves the intrinsic group of A∗∗, but we show that this is always canonically isomorphic to the intrinsic group of L∞(G).
