Given a sequence of balls $(B_n)_{n=1}^\\infty$, we give sufficient conditions for the set of eventually always hitting points to be of full measure. This is the set of points $x$ such that for all large enough $m$, there is a $k < m$ with $T^k (x) \\in B_m$. We also give an asymptotic estimate as $m \\to \\infty$ on the number of $k < m$ with $T^k (x) \\in B_m$. As an application, we prove for almost every point $x$ an asymptotic estimate on the number of $k \\leq m$ such that $a_k \\geq m^t$, where $t \\in (0,1)$ and $a_k$ are the continued fraction coefficients of $x$.", "revisions": [ { "version": "v1", "updated": "2020-10-15T12:44:11.000Z" } ], "analyses": { "subjects": [ "37A50", "37E05", "37D20", "11J70" ], "keywords": [ "hitting points", "asymptotic estimate", "full measure", "exponential decay", "sufficient conditions" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
