- Free actions of compact quantum group on unital C*-algebras (2013, background): “act quantum group (H,∆) on A) iff (1) (δ⊗ id) ◦δ= (id ⊗∆) ◦δ(coassociativity), (2) {δ(a)(1 ⊗ h) | a∈ A,h∈ H}cls = A⊗ min H(counitality). We shall consider three properties of coactions. Definition 0.1 ([E-DA00]). The coaction δ: A→ A⊗min His C∗-free iff (0.4) {(x⊗ 1)δ(y) | x,y∈ A}cls = A⊗ min H. Given ”
