Title: Lexicographic products, wreath products, and generalisations

Speaker: Joy Morris Affiliation: University of Lethbridge Zoom: Contact Soffia Arnadottir

Abstract:

I will present a history and overview of some of the work that has been done on the lexicographic product of graphs, and related generalisations. The focus of my talk will be on the automorphism groups of such graphs, and the relationship to the wreath product of permutation groups.
