Quantum symmetry in multigraphs (part II)

Abstract

This article is a continuation of "Quantum symmetry in multigraphs (part I)". In this article, we give an explicit construction of a non-Bichon type co-action on a multigraph that is, it preserves quantum symmetry of (V,E) in our sense but not always in Bichon's sense. This construction itself is motivated from automorphisms of quantum graphs.
