Core Periphery

Core-periphery structure in networks describes the organization of nodes into densely connected cores and sparsely connected peripheries. Current research focuses on developing improved algorithms for identifying core-periphery structures in various network types, including hypergraphs, and understanding how this structure interacts with other network properties like community structure and influences processes such as information diffusion and innovation. These studies utilize diverse approaches, including random walk models, spectral embeddings, and generative models, to better quantify and understand core-periphery organization. The insights gained are valuable for optimizing network performance in diverse applications, from improving information flow in organizations to accelerating innovation in collaborative settings.
