For weakly hyperbolic such measures (i.e. measures with no zero Lyapunov exponents), we prove that the mean distance/angle between the stable and the unstable Oseledet's bundles gives an upper bound of the sum of the positive Lyapunov exponents and a lower bound of the smallest positive Lyapunov exponent. Some more precise results are proved too.", "revisions": [ { "version": "v2", "updated": "2012-01-23T19:40:33.000Z" } ], "analyses": { "keywords": [ "upper bound", "twisting dynamics", "oseledets splitting", "relationship", "tonelli hamiltonian flows" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.0194A" } } }
