Under mild assumptions on \\tilde\\mu and \\phi, we prove that such a map is exponentially mixing, and satisfies the central and local limit theorems. These results apply to a random walk related to the Farey sequence, thereby answering a question of Guivarc'h and Raugi.", "revisions": [ { "version": "v1", "updated": "2007-03-22T16:53:24.000Z" } ], "analyses": { "subjects": [ "37A25", "37A30", "37A50", "37D25", "37D30" ], "keywords": [ "local limit theorem", "nonuniformly partially hyperbolic skew-products", "farey sequence", "study skew-products", "random walk" ], "note": { "typesetting": "TeX", "pages": 55, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007math......3670G" } } }
