Vertices of the spatial random graph are given as a Poisson point process with intensity $\\lambda>0$. Upon variation of $\\lambda$ there is a percolation phase transition: there exists a critical value $\\lambda_c>0$ such that for $\\lambda<\\lambda_c$ all clusters are finite, but infinite clusters exist for $\\lambda>\\lambda_c$. We identify certain critical exponents that characterize the clusters at (and near) $\\lambda_c$, and show that they agree with the mean-field values for percolation. We derive the exponents through isoperimetric properties of critical percolation clusters rather than via a calculation of the triangle diagram.", "revisions": [ { "version": "v1", "updated": "2025-05-13T23:43:49.000Z" } ], "analyses": { "subjects": [ "60K35", "82B43", "60G55" ], "keywords": [ "random connection model", "hyperbolic space", "mean-field behaviour", "percolation phase transition", "poisson point process" ], "note": { "typesetting": "TeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable" } } }
