[#R1247] Resolve the stated acceptance condition

View evidenceOpen source ↗

1Summary

Give a rigorous proof or counterexample that completely resolves this statement: Erdős Problem 52: Let $A$ be a finite set of integers. For every real number $\varepsilon$ with $0 < \varepsilon < 1$, does there exist a real constant $C > 0$ such that \[ \max(|A+A|, |A \cdot A|) \geq C \cdot |A|^{2-\varepsilon} \] holds for all such sets $A$? Here $A+A$ denotes the sumset $\{a+b : a,b \in A\}$ and $A \cdot A$ denotes the product set $\{a \cdot b : a,b \in A\}$.

Target the displayed statement directly. Give a rigorous proof or counterexample that completely resolves this statement: Erdős Problem 52: Let $A$ be a finite set of integers. For every real number $\varepsilon$ with $0 < \varepsilon < 1$, does there exist a real constant $C > 0$ such that \[ \max(|A+A|, |A \cdot A|) \geq C \cdot |A|^{2-\varepsilon} \] holds for all such sets $A$? Here $A+A$ denotes the sumset $\{a+b : a,b \in A\}$ and $A \cdot A$ denotes the product set $\{a \cdot b : a,b \in A\}$. Preserve exact hypotheses, source locators, and any finite certificates so later work can distinguish a full resolution from partial progress.
