The map g gives rise to generalized Mahler measures for polynomials in one variable. We use diophantine approximation to show that the generalized Mahler measure of a polynomial F at a place v can be computed by averaging the log of the v-adic absolute value of F over the periodic points of g. This allows us to compute canonical heights of algebraic points via equidistribution on periodic points.", "revisions": [ { "version": "v3", "updated": "2007-04-10T23:32:16.000Z" } ], "analyses": { "subjects": [ "11G50", "11J68", "37F10" ], "keywords": [ "generalized mahler measure", "equidistribution", "periodic points", "v-adic absolute value", "nonconstant rational map" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math.....10404S" } } }
