Number Theory", "categories": [ "math.NT" ], "abstract": "14H52 : Elliptic curves Let E be the elliptic curve given by a Mordell equation y^2=x^3-A where A is an integer. For certain A, we use Stoll's formula to compute a lower bound for the proportion of square-free integers D up to X such that the Mordell-Weil rank of the quadratic twist by D is less than 2k, for given non-negative k. We also compute an upper bound for a certain average rank of quadratic twists of E.", "revisions": [ { "version": "v1", "updated": "2005-09-30T18:17:45.000Z" } ], "analyses": { "subjects": [ "14H52" ], "keywords": [ "quadratic twist", "mordell equation", "elliptic curve", "average rank", "stolls formula" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math.....10001C" } } }
