Furthermore, we show Bowen's formula, and the existence and uniqueness of a conformal measure, for a finitely generated expanding semigroup satisfying the open set condition. What we discuss is the `backward iterated function systems', and since the generator maps are not injective in general, we need some efforts to estimate the measure of disks.", "revisions": [ { "version": "v11", "updated": "2005-09-23T02:48:27.000Z" } ], "analyses": { "keywords": [ "expanding rational semigroups", "julia set", "generated expanding semigroup satisfying", "open set condition", "ergodic theory" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 31, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......5522S" } } }
