Our main result is a functional limit theorem of the normalized profile $X_{n,k}/\\mathbb{E}X_{n,k}$ for $k=\\lfloor\\alpha\\log n\\rfloor$ in a certain range of $\\alpha$. A central feature of the proof is the use of the contraction method to prove convergence in distribution of certain random analytic functions in a complex domain. This is based on a general theorem concerning the contraction method for random variables in an infinite-dimensional Hilbert space. As part of the proof, we show that the Zolotarev metric is complete for a Hilbert space.", "revisions": [ { "version": "v2", "updated": "2008-01-22T13:37:41.000Z" } ], "analyses": { "subjects": [ "60F17", "68Q25", "68P10", "60C05" ], "keywords": [ "functional limit theorem", "contraction method", "random analytic functions", "infinite-dimensional hilbert space", "random search trees" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......9385D" } } }
