As a first application of our results we show that the set of parameters corresponding to maps in the quadratic family f_{a}(x) = x^{2}-a which have an absolutely continuous invariant probability measure is at least 10^-5000 !", "revisions": [ { "version": "v3", "updated": "2005-10-07T16:30:43.000Z" } ], "analyses": { "subjects": [ "37D25", "37M99", "37E25" ], "keywords": [ "one-dimensional maps", "non-uniform hyperbolicity", "computable conditions", "occurrence", "absolutely continuous invariant probability measure" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 44, "language": "en", "license": "arXiv", "status": "editable" } } }
