Under the assumption that Gal(K(E[2])/K) = S_3 we show that the density (counted in a non-standard way) of twists with Selmer rank r exists for all positive integers r, and is given via an equilibrium distribution, depending only on a single parameter (the `disparity'), of a certain Markov process that is itself independent of E and K. More generally, our results also apply to p-Selmer ranks of twists of 2-dimensional self-dual F_p-representations of the absolute Galois group of K by characters of order p.", "revisions": [ { "version": "v1", "updated": "2013-03-26T14:26:45.000Z" } ], "analyses": { "subjects": [ "11G05", "11G40", "60J10" ], "keywords": [ "markov model", "arbitrary number field", "absolute galois group", "non-standard way", "elliptic curve" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1303.6507K" } } }
