November follow-up to https://manifold.markets/jim/which-erdos-problems-will-be-solved-080R66NqOU . Only the eight listed problems, not known to be solved at creation, are included. #3 and #571 are excluded because evidence of solutions predates this market.
Each answer resolves independently. The qualifying window starts when this market is created and ends November 30, 2026 at 11:59 pm Pacific Standard Time (December 1, 2026 at 07:59 UTC).
An answer resolves YES if a complete solution to the corresponding numbered Erdős problem first becomes publicly available during that window, with a complete proof (or rigorous counterexample resolving the problem) accepted by the knowledgeable mathematical community. A solution publicly known by the deadline can be verified after the deadline; the deadline concerns the solution becoming public, not the date I resolve the market. Mere claims, partial results, or evidence that does not settle the full stated problem do not qualify. Solutions already publicly available when this market is created do not qualify.
The numbered problem statements and the community-maintained teorth/erdosproblems database (data/problems.yaml) are primary references: erdosproblems/data/problems.yaml at main · teorth/erdosproblems . I will also check the cited mathematical work and credible expert discussion. The erdosproblems.com status display alone is not a required oracle; missing or stale status labels will not override verified mathematical evidence.
An answer resolves NO if no qualifying solution became public within the window. If there is a material unresolved dispute about correctness, the timing, or whether the full problem was solved, or the outcome cannot reliably be determined, that answer resolves N/A rather than guessing. No new answer options may be added.
