We prove that the mapping $f\\in\\mathcal L_1$ is ergodic with respect to the normalized Haar measure on $\\Z_p$ if and only if $f$ induces a single cycle permutation on each residue ring $\\Z/p^k\\Z$ modulo $p^k$, for all $k=1,2,3,...$. The multivariate case, as well as measure-preserving mappings, are considered also. Results of the paper in a combination with earlier results of the author give explicit description of ergodic mappings from $\\mathcal L_1$. This characterization is complete for $p=2$. As an application we obtain a characterization of polynomials (and certain locally analytic functions) that induce ergodic transformations of $p$-adic spheres. The latter result implies a solution of a problem (posed by A.~Khrennikov) about the ergodicity of a perturbed monomial mapping on a sphere.", "revisions": [ { "version": "v1", "updated": "2006-02-05T14:58:41.000Z" } ], "analyses": { "subjects": [ "37A25", "37A05", "11S80", "05.20.-y", "02.30.Cj", "02.30.Sa", "02.10.De" ], "keywords": [ "adic integers", "satisfy lipschitz condition", "induce ergodic transformations", "single cycle permutation", "normalized haar measure" ], "tags": [ "conference paper", "journal article" ], "publication": { "publisher": "AIP", "journal": "AIP Conf.
