The aim of this paper is to extend this normalization result to the case when the vector field is only integrable in the sense of Darboux: the first integrals are of Darboux type and not necessarily analytic, and the commuting vector fields are meromorphic.", "revisions": [ { "version": "v1", "updated": "2018-03-13T13:43:02.000Z" } ], "analyses": { "keywords": [ "normal form", "local analytic poincare-birkhoff normalization", "convergence", "integrability", "analytically integrable vector field admits" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
