Equivalently, the set of their rational points is not thin after a finite extension of the base field. Furthermore, we classify those families of elliptic K3 surfaces over an algebraically closed field which do not admit a second elliptic fibration.", "revisions": [ { "version": "v1", "updated": "2024-04-10T09:16:01.000Z" } ], "analyses": { "subjects": [ "14J28", "14G05", "14J27", "11R45", "06B05" ], "keywords": [ "elliptic k3 surfaces", "non-thin rational points", "second elliptic fibration satisfy", "potential hilbert property", "number field" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
