Article: Prominence and control: The weighted rich-club effect
December 12, 2008
A paper called Prominence and control: The weighted rich-club effect that I have co-authored with Vittoria Colizza
, Pietro Panzarasa, and José Javier Ramasco was published in the October 17 issue of Physical Review Letters (PRL). A pdf version of the paper is available.
Abstract
Complex systems are often characterized by large-scale hierarchical organizations. Whether the prominent elements, at the top of the hierarchy, share and control resources or avoid one another lies at the heart of the global organization and functioning. Inspired by network perspectives, we propose a new general framework for studying the tendency of prominent elements to form clubs with exclusive control over the majority of a system’s resources. We explore associations between prominence and control in the fields of transportation, scientific collaboration, and online communication.
