Specifically, we provide an explicit formula for a supersingular polynomial for rank-2 Drinfeld modules and prove several basic properties. As an application, we give a numerical example of an asymptotically optimal tower of Drinfeld modular curves.", "revisions": [ { "version": "v1", "updated": "2017-01-26T02:05:34.000Z" } ], "analyses": { "subjects": [ "11G09", "11R58" ], "keywords": [ "drinfeld modules", "explicit formula", "supersingular polynomial", "application", "elliptic curves" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
