摘要
对任意,我们在抛物线上构造Hausdorff维数为的Cantor集,使其为Salem集,且每个关联测度满足估计对所有及某个可能依赖于和的常数成立。范围除端点外是最优的。证明基于Laba和Wang关于随机Cantor集限制估计的工作,以及Shmerkin和Suomala关于随机Cantor集上测度的Fourier衰减的工作。他们考虑的分形子集,而我们考虑抛物线的分形子集。

37 pages, 2 figures, Corrected the proof of Proposition 5.1 in v1, added more details in section 3.2 and 5, main results unchanged, ver3: corrected a typo in a math expression in introduction, but it is not related to main theorems. More specifically, $\beta \leq \alpha \leq \alpha_0$ was replaced by $0 \leq \alpha, \beta \leq \alpha_0$ in p2
