We give a construction of a set \(A \subset \mathbb N\) such that any subset \({A' \subset A}\) with \(|A'| \gg |A|^{2/3}\) is neither an additive nor multiplicative Sidon set. In doing so, we refute a conjecture of Klurman and Pohoata.

加法和乘法西顿集

我们给出了一个集合\(A \subset \mathbb N\)的构造,使得任何子集\({A' \subset A}\)\(|A'| \gg |A|^{2/3} \)既不是加法也不是乘法 Sidon 集。通过这样做,我们驳斥了 Klurman 和 Pohoata 的猜想。
