Detecting Core-Periphery Structures by Surprise [PDF]

EPL (Europhysics Letters), 2019
Detecting the presence of mesoscale structures in complex networks is of primary importance. This is especially true for financial networks, whose structural organization deeply affects their resilience to events like default cascades, shocks propagation,

Core-periphery organization of complex networks [PDF]

Physical Review E, 2005
Networks may, or may not, be wired to have a core that is both itself densely connected and central in terms of graph distance. In this study we propose a coefficient to measure if the network has such a clear-cut core-periphery dichotomy.

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.

Assortative and preferential attachment lead to core-periphery networks

Physical Review Research, 2023
Core-periphery is a key feature of large-scale networks underlying a wide range of social, biological, and transportation phenomena. Nodes in the core have an influential position in the network, and thus, the periphery can be under structural ...

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

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 Model [PDF]

, 2019
Core-periphery imbalances and regional disparities figure prominently on the agenda of several disciplines, which result from their enormous impact on economic and social development around the world. In sociology, international relations, and economics, this concept is crucial in explanations of economic exchange.

Chaos in the core-periphery model [PDF]

Journal of Economic Behavior & Organization, 2006
Abstract This paper shows that the standard continuous-time core-periphery model (the foundation of the New Economic Geography) is not robust; simply reformulating it in discrete time has profound implications. The continuous-time model can only exhibit stationary long-term behavior, and high transport costs are perceived as stabilizing. In contrast,

Population mobility and sustainable development in the Mamminasata Metropolitan South Sulawesi, Indonesia [PDF]

Human Geographies: Journal of Studies and Research in Human Geography, 2021
Economic growth and urban agglomeration have triggered an increase in the size and mobility of the Metropolitan Mamminasata urban population. This study aims to analyse spatial interactions working as a determinant of connectivity of the transportation ...

Re-theorising the core: a ‘globalized’ business elite in Santiago, Chile [PDF]

, 1998
World systems theory continues to be a widely adopted approach in theorisations of the contemporary world economy. An important epistemological component to world systems theory is the metaphor of core-periphery.
