We first prove a conjecture of Bubeck, Mossel \\& R\\'acz concerning the influence of the seed graph on the asymptotic behavior of such trees. Separately we study the geometric structure of nodes of large degrees in a plane version of Barab\\'asi-Albert trees via their associated looptrees. As the number of nodes grows, we show that these looptrees, appropriately rescaled, converge in the Gromov-Hausdorff sense towards a random compact metric space which we call the Brownian looptree. The latter is constructed as a quotient space of Aldous' Brownian Continuum Random Tree and is shown to have almost sure Hausdorff dimension $2$.", "revisions": [ { "version": "v1", "updated": "2014-06-06T17:52:34.000Z" } ], "analyses": { "keywords": [ "preferential attachment trees", "seed graph", "scaling limits", "random compact metric space", "brownian continuum random tree" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1406.1758C" } } }
