When K is an imaginary quadratic extension, N is naturally embedded in the unit circle in C and we show that it is equidistributed with respect to inclusion as ordered by the absolute Weil height. By Hilbert's Theorem 90, an element in N can be written as \\alpha/\\bar{\\alpha} for some \\alpha \\in O_K, which yields another ordering of \\mathcal N given by the minimal norm of the associated algebraic integers. When K is imaginary we also show that N is equidistributed in the unit circle under this norm ordering. When K is a real quadratic extension, we show that N is equidistributed with respect to norm, under the map \\beta \\mapsto \\log| \\beta | \\bmod{\\log | \\epsilon^2 |} where \\epsilon is a fundamental unit of O_K.", "revisions": [ { "version": "v1", "updated": "2010-04-06T23:48:39.000Z" } ], "analyses": { "subjects": [ "11M06", "11K36" ], "keywords": [ "quadratic number fields", "algebraic numbers", "equidistribution", "unit circle", "imaginary quadratic extension" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1004.0986P" } } }
