1 Finite Quantum (Hopf) Algebra
Recall that:
Definition 1.1. A finite quantum group QGf is a pair (ℍ, Φ) of a finite-dimensional
C∗-algebra ℍ with a comultiplication Φ such that (ℍ, Φ) is a Hopf ∗-algebra.
Definition 1.2. A finite quantum algebra AGf is the dual of a finite quantum group
as defined above. In the case of a commutative group, its dual commutative Hopf algebra is
obtained by Fourier transformation of its dual finite Abelian quantum group elements.
