Quantum symmetry in multigraphs (part II)

Abstract

This paper is a continuation of Ref. 7. In this paper, we give an explicit construction of a non-Bichon type co-action on a multigraph that is, it preserves quantum symmetry of [Formula: see text] in our sense but not always in Bichon’s sense.2 This construction itself is motivated from automorphisms of quantum graphs.
