OpenAI claim summary for Math-3023
Manuscript 1 (family 318, 2026-09-25): The problem selects the mathematical statement summarized here, including its stated hypotheses and parameter range. The cited theorem gives a claimed counterexample to that assertion in full.
Finite assembly of the height-three chromatic overlap
OpenAI's claim
At prime three and height three, the overlap is claimed to lie outside the ordinary thick subcategory generated by lower local spheres, even allowing arbitrary finite cofibers and retracts of derived-complete sphere modules. The cited manuscript argues for that result; its relation to this problem is specified below.Mathematical statement of the claimed result
Mathematical claim 1.
At prime $3$, with completed sphere $S=S_3^\wedge$, OpenAI claims \[ L_2L_{K(3)}S\notin\operatorname{Thick}\{L_0S,L_1S,L_2S\} \] in the category of $E(2)$-local $S$-modules. Here $L_j$ is $E(j)$-localization, $L_{K(3)}$ is Morava-$K(3)$ localization, and the thick subcategory allows finite cofibers, suspensions and retracts. Thus arbitrary finite attachments, including Moore corrections, cannot assemble this chromatic overlap from the indicated lower-height localized spheres.Outline of the argument
Manuscript 1 (family 318, 2026-09-25): Integral connected and etale markings retain an exceptional norm-character line on the height-two stratum. Full principal-unit action separates that line from every periodicity power carried by the permitted inputs. Comparisons through ordinary finite-stage coefficients and actual homotopy preserve the character across the whole deformation, giving a representation obstruction to any finite assembly.Formal verification
Family 318 has no Lean scope page in this snapshot; no formalization of these manuscript results is listed.This site has not executed the Lean files or checked their dependencies. These descriptions report the scope of the linked declarations, rather than a new verification of the proofs.
Status caveat
OpenAI attributes these results to an internal model. Its release notice cautions that results lacking full formalization can contain mistakes. This site has not independently assessed the proofs; a solved label records the scope of the reported claim.Sources
