Poincaré conjecture →Coverage & review
Coverage of this curation
The accepted topological theorem, smooth formulation, proof ingredients, dimension-four scope and recent formalization evidence.
Formal proofs: Complete Lean proofs of the topological and smooth three-dimensional statements are reported by two external projects. Links below pin the relevant source revisions. Mathlib’s wanted declarations remain statement-only at the inspected revision. No OpenMath proof build or independent correspondence review is recorded.
AI-assisted work: Both formalization projects self-report automated assistance; this attribution is separate from theorem truth and verification evidence.
Search scope & review
Clay’s official description and Morgan–Tian account; Perelman’s finite-extinction paper; Manolescu’s 2026 survey; two 2026 formalization papers, exact public source revisions and the FrenzyMath verification report; Mathlib wanted declarations.
Checked Oct 12, 2026 · independent review pending.
- Selected sources and milestones; this is not an exhaustive literature review.
- Independent mathematical review and OpenMath reproduction of external proof checks remain pending.
