The free operators here are those introduced in [R. Moosa and T. Scanlon, Model theory of fields with free operators in characteristic zero, Preprint 2013]. The proof relies on a new lifting lemma in differential algebra: a differential version of Hensel's Lemma for local finite algebras over differentially closed fields.", "revisions": [ { "version": "v1", "updated": "2014-08-08T19:06:06.000Z" } ], "analyses": { "subjects": [ "03C60", "12H05", "12L12" ], "keywords": [ "free operators", "model companion", "characteristic zero", "partial differential fields", "local finite algebras" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
