We show that for each integer d there exists an explicitly computable closed subset Z of V, not equal to V, such that for each field extension K of k of degree at most d over the field of rational numbers, the set V(K) is Zariski dense as soon as it contains any point outside Z. We also present a version of this statement that is universal over certain twists of V and over all extensions of k. This generalizes a result of Swinnerton-Dyer, as well as previous work of Logan, McKinnon, and the author.", "revisions": [ { "version": "v1", "updated": "2010-09-22T09:31:20.000Z" } ], "analyses": { "keywords": [ "elliptic surfaces", "rational points", "field extension", "number field", "rational numbers" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1009.4306V" } } }
