Connected bipartite graphs of degeneracy exactly r with ex(n,H) ≥ c·n^(2−1/r+1/(28r²)), refuting the Erdős–Simonovits degeneracy conjecture (Erdős problem #146) for every r ≥ 2, with the exact limits of the method. Machine-checked in Lean 4.
CLI toolkit for Erdős problem research: literature ingestion, RAG search, and Lean 4 formalization
Lean 4 formalization of the corrected Erdős Problem 796, proving the second-order asymptotic and explicit kernel-checked bounds.
Mathematical research and the system behind it: eight Erdős problem programmes, Lean proofs, papers on research and writing, experiments and open questions. An independent, AI-assisted prototype by Will Cook.
Plectis: Lean research on Erdős problems. Read it at wcook04.github.io/plectis. This repository holds the website source and the earlier Python toolkit; the Lean proofs are in wcook04/plectis-erdos.
A source-linked index of open math problems solved, refuted, or settled with AI — tracking the July 2026 wave. Verification-status badges, Lean/DRAT certificates, priority caveats.
Lean 4 proof of the extremal half of Erdős problem 1007: a graph of dimension four with nine edges and no isolated vertex is K₃,₃.
Lean 4 proof of the dimension-five variants of Erdős problem 1007: the least edge count of a graph of dimension five is 15, attained by K₆ and K₁,₃,₃.

A continuously re-verified ledger of mathematical records. Mirrors published bounds and constants, re-checks them daily, and goes red when a cited record moves.
Independent exact certification of machine-generated mathematics — exact arithmetic, no code shared with the claimant, refusal as a verdict.
