We thus obtain a continuous function $u(\\theta, c)$ in two variables: the angle $\\theta$ and the cohomology class $c$. As a result, we prove that the Aubry-Mather sets are contained in pseudographs that are vertically ordered by their rotation numbers. Then we characterize the $C^0$ integrable twist maps in terms of regularity of $u$ that allows to see $u$ as a generating function. We also obtain some results for the Lipschitz integrable twist maps. With an example, we show that our choice is not the so-called discounted one (see \\cite{DFIZ2}), that is sometimes discontinuous. We also provide examples of `strange' continuous foliations that cannot be straightened by a symplectic homeomorphism.", "revisions": [ { "version": "v1", "updated": "2018-09-07T09:38:24.000Z" } ], "analyses": { "subjects": [ "37E40", "37J50", "37J30", "37J35" ], "keywords": [ "symplectic twist map", "transversal dependence", "cohomology class", "lipschitz integrable twist maps", "symplectic homeomorphism" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
