Using the methods developed in \\cite{1}, we prove that the \\emph{admissible rotation set} is convex, and the periodic trajectories of admissible type are dense in the admissible rotation set. In addition, we show that the admissible rotation set is a proper subset of the general rotation set.", "revisions": [ { "version": "v1", "updated": "2016-03-11T05:38:16.000Z" } ], "analyses": { "keywords": [ "admissible rotation set", "general rotation set", "specific kind", "periodic trajectories", "proper subset" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer" }, "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160303527A" } } }
