The case of study considered is the preprint archive at cul.arxiv.org. Each node corresponds to a scientist, and a link is present whenever two authors wrote a paper together. This graph is a nice example of degree-assortative network, that is, to say a network where sites with similar degree are connected to each other. The model presented is one of the few able to reproduce such behavior, giving some insight on the microscopic dynamics at the basis of the graph structure. publisher: American Physical Society date: 2004-09 type: Article type: PeerReviewed identifier: Catanzaro, Michele and Caldarelli, Guido and Pietronero, Luciano Assortative model for social networks.
