We prove that in this regime, the fluctuations of extreme eigenvalues are given by the Tracy-Widom distribution. As a consequence, about 69% of $d$-regular graphs have all nontrivial eigenvalues bounded in absolute value by $2\\sqrt{d-1}$.", "revisions": [ { "version": "v1", "updated": "2023-05-02T13:58:10.000Z" } ], "analyses": { "subjects": [ "60B20", "05C80" ], "keywords": [ "random regular graphs", "edge universality", "growing degrees", "extreme eigenvalues", "tracy-widom distribution" ], "note": { "typesetting": "TeX", "pages": 53, "language": "en", "license": "arXiv", "status": "editable" } } }
