Quantum automorphism group of the lexicographic product of finite regular graphs (1504.05671v1)
Published 22 Apr 2015 in math.QA, math.CO, and math.OA
Abstract: We study the quantum automorphism group of the lexicographic product of two finite regular graphs, providing a quantum generalization of Sabidussi's structure theorem on the automorphism group of such a graph.
