In this article we study the structure of the dynamics on the Julia set, which is typically larger than $Supp(\\mu)$. The Julia set is the support of the so-called Green current $T$, so it admits a natural filtration by the supports of the exterior powers of $T$. For $1\\leq q \\leq k$, let $J_q= Supp(T^q)$. We show that for a generic point of $J_q\\setminus J_{q+1}$ there are at least $(k-q)$ \"Fatou directions\" in the tangent space. We also give estimates for the rate of expansion in directions transverse to the Fatou directions.", "revisions": [ { "version": "v2", "updated": "2012-03-26T21:04:05.000Z" } ], "analyses": { "keywords": [ "julia set", "fatou directions", "maximal entropy measure", "green current", "holomorphic endomorphisms" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1006.0882D" } } }
