In particular, the main theorem provides the convergence, in the Kantorovich-Rubinstein metric, of the rank of a randomly chosen vertex in graphs generated via either a directed configuration model or an inhomogeneous random digraph. The theorem fully characterizes the limiting distribution by expressing it as a random sum of i.i.d.~copies of the attracting endogenous solution to a branching distributional fixed-point equation. In addition, we provide the asymptotic tail behavior of the limit and use it to explain the effect that in-degree/out-degree correlations in the underlying graph can have on the qualitative performance of PageRank.", "revisions": [ { "version": "v1", "updated": "2019-09-21T00:04:50.000Z" } ], "analyses": { "subjects": [ "05C80", "60J80", "68P20", "41A60", "37A30", "60B10" ], "keywords": [ "pageranks behavior", "degree-degree correlations", "asymptotic tail behavior", "googles pagerank algorithm", "branching distributional fixed-point equation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
