On démontre que le groupe quantique d’automorphismes du graphe de Clebsch est ce qui répond à une question de Banica, Bichon et Collins de 2007. En général, pour des valeurs impaires de n, le groupe quantique d’automorphisme du graphe du n-cube plié est . En plus, on démontre qu’un graphe possède des symétries quantiques, si son groupe d’automorphismes contient une paire d’automorphismes disjoints.
We show that the quantum automorphism group of the Clebsch graph is . This answers a question by Banica, Bichon and Collins from 2007. More general for odd , the quantum automorphism group of the folded -cube graph is . Furthermore, we show that if the automorphism group of a graph contains a pair of disjoint automorphisms this graph has quantum symmetry.
