We also observe that, despite the corresponding statement is also true for $k = 2$, it is false for $k = 3$.", "revisions": [ { "version": "v1", "updated": "2020-10-29T00:34:57.000Z" } ], "analyses": { "keywords": [ "lagrange spectra", "initial segments", "dynamical characterization", "lagrange dynamical spectra", "horseshoes" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
