By using Bestvina-Handel theory, as well as some further improvements, the eigengroups of a given automorphism of $F$ (and its fixed subgroup among them) are globally analyzed and described. In particular, an explicit description of all subgroups of $F$ which occur as the fixed subgroup of some automorphism is given.", "revisions": [ { "version": "v1", "updated": "2003-06-26T15:42:04.000Z" } ], "analyses": { "subjects": [ "20E05", "20E36" ], "keywords": [ "auto-fixed subgroups", "bestvina-handel theory", "automorphism", "finitely generated free group", "explicit description" ], "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003math......6380M" } } }
