AI总结:

本文改进了乘法Sidon集最大间隙的上界,将指数从约0.47降至10/33≈0.303。

摘要:

设 $\rho = \frac{13-\sqrt{69}}{10} \approx 0.47$,近期已证明在 $\{1, 2, \ldots, n\}$ 中存在乘法Sidon集(即无任何非平凡解 $ab = cd$ 的集合),其最大间隙大小 $\ll_{\varepsilon} n^{\rho + \varepsilon}$。本文改进了这一结果,证明可取 $\rho = \frac{10}{33} \approx 0.303$。

英文摘要:

With $ρ= \frac{13-\sqrt{69}}{10} \approx 0.47$, it was recently established that there exist multiplicative Sidon sets (sets without any non-trivial solutions to $ab = cd$) in $\{1, 2, \ldots, n\}$ with maximal gap size $\ll_{\varepsilon} n^{ρ+ \varepsilon}$. Here we improve upon this result and show that one can take $ρ= \frac{10}{33} \approx 0.303$ instead.
