Sublinear domination and core–periphery networks [PDF]
Scientific Reports, 2021 In this paper we devise a generative random network model with core–periphery properties whose core nodes act as sublinear dominators, that is, if the network has n nodes, the core has size o(n) and dominates the entire network.

Core-periphery structure in directed networks. [PDF]
Proc Math Phys Eng Sci, 2020 Empirical networks often exhibit different meso-scale structures, such as community and core–periphery structures. Core–periphery structure typically consists of a well-connected core and a periphery that is well connected to the core but sparsely connected internally. Most core–periphery studies focus on undirected networks.

Atypical core-periphery brain dynamics in autism [PDF]
Network Neuroscience, 2021 The intrinsic function of the human brain is dynamic, giving rise to numerous behavioral subtypes that fluctuate distinctively at multiple timescales.

Analysis of Core–Periphery Structure Based on Clustering Aggregation in the NFT Transfer Network [PDF]
EntropyWith the rise of blockchain technology and the Ethereum platform, non-fungible tokens (NFTs) have emerged as a new class of digital assets. The NFT transfer network exhibits core–periphery structures derived from different partitioning methods, leading ...

A simulated annealing heuristic for maximum correlation core/periphery partitioning of binary networks. [PDF]
PLoS ONE, 2017 A popular objective criterion for partitioning a set of actors into core and periphery subsets is the maximization of the correlation between an ideal and observed structure associated with intra-core and intra-periphery ties.

Task-based core-periphery organization of human brain dynamics. [PDF]
PLoS Computational Biology, 2013 As a person learns a new skill, distinct synapses, brain regions, and circuits are engaged and change over time. In this paper, we develop methods to examine patterns of correlated activity across a large set of brain regions.

Sparse networks with core-periphery structure [PDF]
Electronic Journal of Statistics, 2021 We propose a statistical model for graphs with a core-periphery structure. To do this we define a precise notion of what it means for a graph to have this structure, based on the sparsity properties of the subgraphs of core and periphery nodes. We present a class of sparse graphs with such properties, and provide methods to simulate from this class ...

Core-Periphery Detection in Hypergraphs
SIAM Journal on Mathematics of Data Science, 2023 Core-periphery detection is a key task in exploratory network analysis where one aims to find a core, a set of nodes well-connected internally and with the periphery, and a periphery, a set of nodes connected only (or mostly) with the core. In this work we propose a model of core-periphery for higher-order networks modeled as hypergraphs and we propose
