We ask if we can choose such a parametrisation of an elliptic curve to reflect the field over which it is defined: this can be viewed as a generalisation of the Shimura-Taniyama-Weil conjecture.", "revisions": [ { "version": "v1", "updated": "2002-10-24T17:59:25.000Z" } ], "analyses": { "keywords": [ "elliptic curve", "congruence defects", "belyi parametrisations", "finite index subgroups", "number fields" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2002math.....10391K" } } }
