Zeta23.Statement has `IsNontrivialZero ρ`, `zeroMult`, `zerosIn`, `Ncount`, etc., and Mathlib has `RiemannHypothesis` (used at line 137: `theorem RH_implies_on_line (hRH : RiemannHypothesis)`). Mathlib indeed has `RiemannHypothesis` defined (Mathlib.NumberTheory.LSeries.RiemannZeta or similar). Now I can write the skeleton. Key statements for NguyenRH1: **LiSkeleton.lean:** - Define `liCoeff (n : ℕ) : ℂ`? The actual λ_n = Σ_ρ [1−(1−1/ρ)ⁿ] over nontrivial zeros with multiplicity — an infinite sum needing convergence. For a skeleton, define via `∑'` (tsum) over a subtype? That's heavy. Standard trick: state finitary versions. For skeleton purposes: ```lean import Mathlib import Zeta23.Statement noncomputable def liCoeff (n : ℕ) : ℂ := ∑' ρ : {ρ // IsNontrivialZero ρ}, (1 - (1 - 1/ρ)^n) * (zeroMult ρ : ℂ) ``` Convergence unknown (that's part of the content) — tsum of non-summable is 0 in Lean, which makes the statement vacuously... risky but it's a skeleton; document it. Alternatively define partial sums over zerosIn windows. Honest skeleton: state the theorem with the definition plus a `Summable` hypothesis? Cleaner: follow the finite-height nature of our theorem: the bridge only needs zeros to height √n+1. Honestly, for a *skeleton* the deliverable is compilable statements whose proofs are sorry. I'll define: ```lean /-- The Keiper–Li coefficients (statement-level skeleton; convergence content isolated in `liCoeff_summable`). -/ noncomputable def liCoeff (n : ℕ) : ℂ := ... ``` - `theorem S_infty_lower_bound (n : ℕ) (hn : 20 ≤ n) : ...` — S_∞ defined via the exact identity sum over odd m. Define: ```lean noncomputable def SInfty (n : ℕ) : ℝ := (1 - a1) * n - 1 + ∑' m : {m // Odd m ∧ 3 ≤ m}, ((1 - 1/m)^n - 1 + n/m) ``` Hmm, summability again. This is getting deep. For a first skeleton, simpler: define SInftyLower and state the bound on the *actual* S_∞ via its Lagarias series definition... Let me simplify honestly: the skeleton states, over explicitly given real sequences, the analytic facts we proved: 1. `sInfty_lower`: for the explicit function S_∞(n) (defined by the exact odd-m identity as an ℝ tsum), the lower bound holds for n ≥ 20. (proof sorry) 2. `margin_convex`: the explicitly defined margin function (given B(n) with named constants) is convex on [20, ∞) / second derivative ≥ 0 — state as `ConvexOn ℝ (Set.Ici 20) margin` with margin defined explicitly. The definition of margin needs C₀(T), N(T)... I can define these as abstract functions with hypothesis-driven properties? For a statement skeleton, define margin as an explicit ℝ→ℝ function using Real.log and a parameter C₀ : ℝ → ℝ with hypothesis `hC0 : ∀ t, C₀ t ≤ 0.433 * Real.log (t+2) + ...`. Hmm — but then convexity isn't true for arbitrary C₀. Reality check: full statement-faithful skeletons require real design. The pragmatic Phase-5-first-pass deliverable (honest, compilable): - LiSkeleton: liCoeff definition + the finite-height theorem statement with hypothesis hRH_height : ∀ ρ, IsNontrivialZero ρ → ρ.im ≤ T0 → ρ.re = 1/2 (i.e., "RH verified to height T₀" as a Prop), plus finite-verification hypothesis. That mirrors Zeta23's hypothesis-driven style exactly. - SInfty/margin: state as real-analysis lemmas with fully explicit definitions where cheap (S_∞ via odd-m tsum is actually fine as a definition), proofs sorry. - SuzukiSkeleton: state the factorization as an equation between explicitly named entire functions? The objects (W, V±) need Suzuki's constructions — state abstractly: variables W F R0 : ℂ → ℂ with the relation as a hypothesis? That's vacuous. Better honest skeleton: define F(z) = z²ξ(½−iz)/ξ'(½−iz) explicitly (Mathlib has riemannZeta; ξ maybe not — define ξ via completed zeta... Mathlib has `riemannXi`? I believe Mathlib has completedRiemannZeta (Λ) and `riemannXi`? There is `Complex.completedRiemannZeta` and `completedRiemannZeta₀`... not sure about xi. Defining ξ from Λ: ξ(s) = Λ(s)... actually completedRiemannZeta IS ξ-ish. I can write `noncomputable def xi (s : ℂ) : ℂ := completedRiemannZeta s`? Risky without checking names. Given I can compile-check later (build will be available), I can iterate: write skeleton, compile, fix errors. That's the loop. Keep skeleton v1 minimal: LiSkeleton with 3 statements, SuzukiSkeleton with the factorization stated over W as a given function family + F explicit... Actually, let me reconsider scope: the honest, valuable, achievable 5.1 deliverable this session: 1. Toolchain + full `lake build` of zeta-23-lean (completes D-007's deferred rebuild → 5.2's foundation). 2. Run the AUDIT.md #print axioms commands → 5.2 verified live (not just static). 3. NguyenRH1 package with skeleton statements for T-1's elementary lemmas (S_∞ lower bound, margin convexity as real-function statements with explicit definitions) + finite-height Li theorem (hypothesis-driven, Zeta23 style), compiling with sorry, with #print axioms showing sorryAx (documented as the skeleton marker). 4. Suzuki/valley skeletons: statement stubs only if cleanly expressible; otherwise documented as deferred (needs model-space infrastructure) — consistent with Appendix B. Check build progress. The cache fetch may still be running. Let me write the package files now, then poll. For Mathlib v4.33: `RiemannHypothesis` exists in Mathlib (Mathlib/NumberTheory/LSeries/RiemannZeta.lean? it's in Mathlib.NumberTheory.LSeries.RiemannZeta — `def RiemannHypothesis : Prop := ∀ (s : ℂ) (_ : riemannZeta s = 0) (_ : s.im ≠ 0)...`? Zeta23/Statement.lean:137 uses it, and Statement imports what? Let me check imports of Statement.lean to mirror them.
Let me check Statement.lean's imports and the exact `RiemannHypothesis` usage to mirror conventions.
