设x ∈ [0,1)和[a1(x),a2(x),.]是x的连分式展开式。对于任何n = 1,请写入。Khintchine(1935)数学1 361-82)证明了,收敛于关于的测度,其中表示一维勒贝格测度。菲利普(1988年)。数学105 195-206)表明,不存在一个合理的归一化序列,使得满足强大数定律。在本文中,我们证明了对任何α ≠ 0,集合的Hausdorff维数为1。此外,我们证明了由实数组成的集合的Hausdorff维数是1,其中实数的部分幂和以给定的多项式速率增长。
Let x ∊ [0, 1) and [a1(x), a2(x), …] be the continued fraction expansion of x. For any n ⩾ 1, write . Khintchine (1935 Compos. Math. 1 361–82) proved that converges in measure to with respect to , where denotes the one dimensional Lebesgue measure. Philipp (1988 Monatsh. Math. 105 195–206) showed that there is not a reasonable normalizing sequence such that a strong law of large numbers is satisfied. In this paper, we show that for any α ⩾ 0, the set is of Hausdorff dimension 1. Furthermore, we prove that the Hausdorff dimension of the set consisting of reals whose sums of partial quotients grow at a given polynomial rate is 1.
