We propose an analog of Deift-Kriecherbauer-McLaughlin-Venakides-Zhou asymptotic method for the analysis of the relevant dbar-problem, and indicate how familiar steps for the Hermitian model, e.g. the g-function ``undressing'', might look like in the case of the normal model. We use the particular model considered recently by P. Elbau and G. Felder as a case study.", "revisions": [ { "version": "v1", "updated": "2007-08-28T22:51:48.000Z" } ], "analyses": { "keywords": [ "orthogonal polynomials", "complex plane", "deift-kriecherbauer-mclaughlin-venakides-zhou asymptotic method", "related normal matrix model", "related hermitian model" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0708.3867I" } } }
