Free Product Formulae for Quantum Permutation Groups
Associated to a finite graph X is its quantum automorphism group G(X). We prove a formula of type G(X ∗ Y ) = G(X) ∗w G(Y ), where ∗w is a free wreath product. Then we discuss representation theory of free wreath products, with the conjectural formula μ(G ∗w H) = μ(G) ⊠ μ(H), where μ is the associated spectral measure. This is verified in two situations: one using free probability techniques, t...
متن کاملAlgebraic Quantum Permutation Groups
We discuss some algebraic aspects of quantum permutation groups, working over arbitrary fields. If K is any characteristic zero field, we show that there exists a universal cosemisimple Hopf algebra coacting on the diagonal algebra K: this is a refinement of Wang’s universality theorem for the (compact) quantum permutation group. We also prove a structural result for Hopf algebras having a non-...
متن کاملFree Wreath Product by the Quantum Permutation Group
Let A be a compact quantum group, let n ∈ N∗ and let Aaut(Xn) be the quantum permutation group on n letters. A free wreath product construction A∗wAaut(Xn) is done. This construction provides new examples of quantum groups, and is useful to describe the quantum automorphism group of the n-times disjoint union of a finite connected graph.
متن کاملIntegration over Quantum Permutation Groups
A remarkable fact, discovered by Wang in [14], is that the set Xn = {1, . . . , n} has a quantum permutation group. For n = 1, 2, 3 this is the usual symmetric group Sn. However, starting from n = 4 the situation is different: for instance the dual of Z2 ∗ Z2 acts on X4. In other words, “quantum permutations” do exist. They form a compact quantum group Qn, satisfying the axioms of Woronowicz in...
متن کاملTwisted sectors for tensor product VOAs associated to permutation groups
Let V be a vertex operator algebra. It is shown that the categories of weak, admissible and ordinary g-twisted modules for the tensor product VOA V ⊗k are isomorphic to the categories of weak, admissible and ordinary V -modules respectively where g is a k cycle automorphism of V ⊗k. For arbitrary permutation automorphism g of V ⊗k the category of admissible g-twisted modules for V ⊗k is semi si...
