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...

in this paper, we verify the solvability of free product of finite cyclic groups with topological methods. we use cayley graphs and everitt methods to construct suitable 2-complexes corresponding to the presentations of groups and their commutator subgroups. in particular, using these methods, we prove that the commutator subgroup of $mathbb{z}_{m}*mathbb{z}_{n}$ is free of rank $(m-1)(n-1)$ fo...
