Density-based and Transport-based Core-periphery Structures in Networks

This paper will examine core-periphery structures in a wide range of examples of transportation, social, and financial networks—including road networks in large urban areas, a rabbit warren, a dolphin social network, a European interbank network, and a migration network between counties in the United States. Networks often possess mesoscale structures, and studying them can yield insights into both structure and function. In such structures, core network components are well-connected both among themselves and to peripheral components, which are not well-connected to anything. The authors will illustrate how a recently developed transport-based notion of node coreness is very useful for characterizing transportation networks. The authors also examine core versus peripheral edges and show that the resulting diagnostic is also useful for transportation networks. The authors develop a family of generative models of road networks in order to further examine the properties of transportation networks. The paper illustrates the effect of the dimensionality of the embedding space on transportation networks and correlations between different measures of coreness can be very different for different types of networks.
