广义差集与自相关积分

Generalized difference sets and autocorrelation integrals

Noah Kravitz

摘要:

在2010年,Cilleruelo,Ruzsa和Vinuesa在第一个$N$自然数中广义Sidon集的最大可能大小与关于$[0,1]$上的非负值函数的“模拟”问题中的最佳常数之间建立了令人惊讶的联系,其中自卷积积分一致有界。在Barnard和Steinerberger最近提出的一个问题的基础上,我们证明了关于复盖第一个$N$自然数的所谓广义差集的最小尺寸和关于$\mathbb{R}$上的非负值函数的类似问题中的最优常数的相应对偶结果,其中自相关积分在$[0,1]$上有界.这些结果表明,Cilleruelo,Ruzsa和Vinuesa的对应关系是一个更普遍的现象,在连续世界的问题添加剂组合学的离散问题的代表。

英文摘要:

In 2010, Cilleruelo, Ruzsa, and Vinuesa established a surprising connection between the maximum possible size of a generalized Sidon set in the first $N$ natural numbers and the optimal constant in an ``analogous'' problem concerning nonnegative-valued functions on $[0,1]$ with autoconvolution integral uniformly bounded above. Answering a recent question of Barnard and Steinerberger, we prove the corresponding dual result about the minimum size of a so-called generalized difference set that covers the first $N$ natural numbers and the optimal constant in an analogous problem concerning nonnegative-valued functions on $\mathbb{R}$ with autocorrelation integral bounded below on $[0,1]$. These results show that the correspondence of Cilleruelo, Ruzsa, and Vinuesa is representative of a more general phenomenon relating discrete problems in additive combinatorics to questions in the continuous world.
