Mathematical research progress

A public, evidence-graded record of what has actually been proved, what has a machine-checked proof candidate, what is only partially formalized, and what remains open. Updated 15 July 2026.

Strongest completed work

OEIS A317940 positivity

Lean verified

The exact Formal Conjectures theorem is discharged, and the formal development proves the stronger strict positivity statement for every positive input.

Written on the Wall II — Conjecture 65

Exact Lean theorem

A short structural argument bounds both custom distance terms and supplies a two-vertex induced forest. Dedicated CI and an axiom audit passed.

Written on the Wall II — Conjecture 316

Machine-verified proof candidate

The exact research-open Formal Conjectures statement has a full Lean proof based on classifying the non-pendant core and the minimal total dominating sets.

Erdős 602 countable-index variant

Exact Lean theorem

A direct recursive Bernstein-style coloring proves the exact repository variant. The proof actually uses only infinitude of each indexed set.

Erdős 1150 Parseval variant

Exact Lean variantMain conjecture open

Discrete Fourier orthogonality and Parseval prove sup |P(z)| ≥ √(n+1). The stronger uniform (1+c)√n research conjecture is not solved.

Checkerboard four-direction program

Paper proof packagePartial LeanAll slopes open

New defect-moment bounds and a claimed exact four-direction LP limit at α≈1.5768233969. The actual every-slope checkerboard NTIL lower bound remains open.

WOWII 143Complete modular Lean proof; independent kernel-audit infrastructure is under review.Proof source exists and compiles; external novelty and upstream acceptance remain separate.

Erdős 865Exact-statement bridge and independent kernel verification are complete.The underlying combinatorial solution is external and explicitly credited.

Major active research campaigns

Erdős 885

Deep arithmetic-geometry progressNot solved

Normalized square-addition packets, five elliptic quotients, rank/Selmer computations, multi-level Mordell–Weil sieves, ghost-tower analysis, and a current product-localization certification branch.

WOWII 314

Paper proof / Lean frontier

A structural classification reduces connected triangle-free induced-P5-free graphs to chain-graph and complete-C5-blow-up families. One global top-level lemma remains.

Goldbach campaign

Conditional reductionsNo proof

The work isolated the parity obstruction, a reflected Möbius correlation, and a conditional rough-sieving bridge. None of this currently constitutes a proof of Goldbach.

Finite checkerboard frontier

Exact computation

The campaign narrowed Dmono(22) to 33 or 34, with many canonical boundary cases eliminated and no 34-point witness found.

Truth-in-labeling policy

A green Lean build proves only the theorem actually stated in the checked file. A finite computation is not an asymptotic proof. A paper proof draft is not yet peer review. A result can be formally correct but not historically novel. Every project page records these boundaries explicitly.
