Title: An Upper Bound on Graphical Partitions

Speaker: Steve Melczer Affiliation: UQAM/CRM Zoom Contact Karen Yeats

Abstract:

An integer partition is called graphical if it can be realized as the size-ordered degree sequence of a simple graph (with no loops or multiple edges).  In his 1736 paper on the Königsberg bridge problem, arguably the origin of graph theory, Euler gave a necessary condition for a partition to be graphical: its sum must be even.
