Proof of Theorem 7.4 corrected, as well as some other minor corrections", "categories": [ "math.DS", "math.CV" ], "abstract": "Let f be a transcendental meromorphic function. Suppose that the finite part of the postsingular set of f is bounded, that f has no recurrent critical points or wandering domains, and that the degree of pre-poles of f is uniformly bounded. Then we show that f supports no invariant line fields on its Julia set. We prove this by generalizing two results about rational functions to the transcendental setting: a theorem of Mane about the branching of iterated preimages of disks, and a theorem of McMullen regarding absence of invariant line fields for \"measurably transitive\" functions. Both our theorems extend results previously obtained by Graczyk, Kotus and Swiatek.", "revisions": [ { "version": "v3", "updated": "2010-08-06T15:43:53.000Z" } ], "analyses": { "subjects": [ "37F10", "30D05", "37D25", "27F15", "37F35" ], "keywords": [ "non-recurrent transcendental functions", "manes theorem", "invariant line fields", "theorems extend results", "transcendental meromorphic function" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0802.0666R" } } }
