We study the fractal properties of their orbits. For this purpose, we introduce a new notion, the \\emph{continuous time length of $\\varepsilon$-neighborhoods of the orbits}, and prove that this function of $\\varepsilon$ admits an asympotic expansion in terms of transseries. Given a parabolic Dulac germ, we prove that this expansion determines its class of formal conjugacy, and compute its Fatou coordinate.", "revisions": [ { "version": "v1", "updated": "2016-06-08T14:38:05.000Z" } ], "analyses": { "subjects": [ "34C20", "37C10", "39B12", "46A19", "28A75", "58K50", "26A12" ], "keywords": [ "dulac maps", "epsilon-neighborhoods", "analytic planar vector fields", "parabolic dulac germ", "first return maps" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
