We obtain asymptotic formulae that describe the behavior of $U_n$ as $n\\to\\infty$, in terms of certain bounded arithmetic functions with a doubling periodicity property. As previously shown in \\cite{LopMc2}, after properly translating and scaling $U_n$, one obtains a new sequence $(F_n)$ that is bounded and divergent. We find the exact value of $\\liminf F_n$ (the value of $\\limsup F_n$ was already given in \\cite{LopMc2}), and show that the interval $[\\liminf F_n,\\limsup F_n]$ comprises all the limit points of the sequence $(F_n)$.", "revisions": [ { "version": "v1", "updated": "2023-09-08T15:37:37.000Z" } ], "analyses": { "subjects": [ "31C20", "31A15", "11M06" ], "keywords": [ "greedy energy sequences", "unit circle", "optimal values", "bounded arithmetic functions", "limit points" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
