We show this for some classes of derived from Anosov (DA) and non-uniformly hyperbolic systems with dominated splitting, in particular for examples described by Bonatti and Viana.", "revisions": [ { "version": "v1", "updated": "2023-10-10T14:30:43.000Z" } ], "analyses": { "keywords": [ "lyapunov exponents", "anosov diffeomorphisms", "volume preserving partially hyperbolic diffeomorphisms", "linear anosov automorphism", "non-uniformly hyperbolic systems" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
