On the Connectivity and the Diameter of Betweenness-Uniform Graphs

Combinatorics 2023-09-11 v2 Discrete Mathematics

Abstract

Betweenness centrality is a centrality measure based on the overall amount of shortest paths passing through a given vertex. A graph is betweenness-uniform if all its vertices have the same betweenness centrality. We study the properties of betweenness-uniform graphs. In particular, we show that every connected betweenness-uniform graph is either a cycle or a 33-connected graph. Also, we show that betweenness uniform graphs of high maximal degree have small diameter.
