关于连分数极值理论的一个注记

数论 2016-08-30 v2

摘要

xx为单位区间内的无理数,记其连分数展开为[a1(x),a2(x),,an(x),][a_1(x), a_2(x), \cdots, a_n(x), \cdots]。对于任意n1n \geq 1,记Tn(x)=max1kn{ak(x)}T_n(x) = \max_{1 \leq k \leq n}\{a_k(x)\}。我们关注分形集Eϕ={x(0,1):limnTn(x)ϕ(n)=1}, E_\phi = \left\{x \in (0,1): \lim_{n \to \infty} \frac{T_n(x)}{\phi(n)} =1\right\}, 的 Hausdorff 维数,其中ϕ\phi是定义在N\mathbb{N}上的正函数,且当nn \to \inftyϕ(n)\phi(n) \to \infty。Wu 和 Xu、Liao 和 Rams 以及 Ma 已获得了一些部分结果。在本文中,当ϕ(n)\phi(n)nn趋于无穷大而以双指数速率趋于无穷大时,我们进一步研究了这一课题。

备注

10 pages. Some metric results on the extreme value theory for continued fractions are parallel to the classical results of i.i.d. random variables with Pareto-type distributions. This remark just collects some interesting results on the extreme value theory for continued fractions from the fractal points of view. The method in the proof of our main result is inspired by Xu
