ZFCρ Paper LIX: Spectral Ratio Boundedness and the Two-Conjecture Closure of H'

DOI: 10.5281/zenodo.19480519  ·  CC BY 4.0

§1. Introduction

1.1. Status after Paper 58

Paper 58 reduced H' on the deterministic spectral/Dirichlet route to two explicit conjectures:

  • Conjecture 58.1 (Cross-product screening): For all sufficiently large j, sub-blocks at screening scale have nonpositive cross-product sum.
  • Conjecture 58.2 (Spectral derivative bound): 2^j · (B^{(1)})² ≤ C for all large j.

Under 58.1 + 58.2 + SD (unconditional, Paper 50): H' follows.

1.2. What this paper does

Three rounds of experiments and multi-AI review lead to:

(i) Falsification of Conjecture 58.1. The cross-product sign is oscillatory, not eventually negative.

(ii) Replacement. Conjecture 59.1 (R_wt = O(1)) replaces 58.1 as the canonical DSF conjecture, supported by 19 consecutive j-values.

(iii) BL mechanism correction. The spectral derivative is small because of exponential baseline decay (analytic), not antisymmetric cancellation (false).

(iv) Refinement of 58.2. Conjecture 59.2 sharpens the BL condition with a uniform-in-t formulation.

(v) Complete closure chain. 59.1 + 59.2 + SD → H' is proved with no hidden assumptions.

1.3. Notation

All notation follows Papers 50–51. In particular:

  • h(p) = η(p) − μ₁₂(p mod 12) (character-stripped residual)
  • B_j = Σ_{p∈I_j} h(p)/p (dyadic block sum), I_j = [2^j, 2^{j+1})
  • D_j = Σ_{p∈I_j} (h(p)/p)² (diagonal)
  • R_wt = B_j² / (j · D_j) (weighted spectral ratio, Paper 56)
  • E_j(t) = Σ_{p∈I_j} h(p)/p · (p^{-it} − e^{-it·c_j}), c_j = (j+½)ln 2
  • B_j^{(1)} = Σ_{p∈I_j} h(p)/p · (log p − c_j) (first spectral derivative)

§2. Fine-grained j-scan

2.1. Experimental design

Previous papers (53–58) tested only j = 14, 17, 20, 23, 26, 29, 32 (spacing 3). This paper scans every integer j from 14 to 33, using N = 10¹⁰ with the rho binary (P32 convention, λ = 3.856763).

Each block is processed in a single streaming pass computing B_j, D_j, B_j^{(1)}, R_wt, and cross-product sums at five sub-block scales (n* = 500, 2000, 10000, 50000, 200000).

2.2. Data

Note: j = 33 excluded (truncated block: N = 10¹⁰ < 2³⁴, m_j = 61M vs expected ~370M).

2.3. R_wt damped oscillation

R_wt exhibits clear damped oscillation:

  • Peak 1: j ≈ 21–23, R_wt ≈ 25.
  • Trough 1: j = 27, R_wt = 0.79.
  • Peak 2: j = 30, R_wt = 20.3.
  • Trough 2: j = 32, R_wt = 2.70.

Period ≈ 7–9 in j, consistent with Paper 55's T = 8 = 2³. Amplitude decays: peaks 25 → 20, troughs 0.8 → 2.7. All 19 values fall within [0.79, 25.3].


§3. Falsification of Conjecture 58.1

3.1. Cross-product sign is oscillatory

Conjecture 58.1 stated that for sufficiently large j, the cross-product sum at screening scale is nonpositive. The j-scan reveals:

  • Negative: j = 27, 28, 31, 32 (R_wt troughs).
  • Positive: j = 29, 30 (R_wt peaks), and all j ≤ 26.

The cross-product sign tracks the R_wt oscillation cycle. It is not eventually negative.

3.2. B⁰ sign also oscillates

B_j = Σ h(p)/p changes sign at j = 28: negative for j ≤ 27, positive for j = 28–31, negative again at j = 32. This is the damped oscillation in the cumulative sum of h/p.

3.3. Consequence

Conjecture 58.1 is false in its stated form. The "eventual screening" and "adaptive screening scale" reformulations are also invalidated: cross-product negativity is a phase-dependent phenomenon, not an asymptotic one. The Paper 52 Theorem 3.1 route (cross-product → deterministic DSF) cannot be applied at every large j.


§4. Conjecture 59.1: Spectral Ratio Boundedness

4.1. Statement

Conjecture 59.1. There exists a constant C > 0 such that for all j ≥ 1:

R_wt := B_j² / (j · D_j) ≤ C.

Equivalently: I_j(0) ≤ C · j · D_j (Paper 51 spectral target).

4.2. Relation to prior work

Paper 56 first identified R_wt = O(1) as the front-door conjecture. Paper 57 provided a conditional bridge from screened covariance to expectation-level R_wt decay. The present paper confirms R_wt = O(1) with 19 data points and elevates it to the canonical DSF statement.

4.3. Mechanism vs statement

The damped oscillation of Paper 55 (rebound ratio r ≈ 0.80, absorption rate η ≈ 0.20, period T = 8 = 2³) provides the structural explanation for why R_wt is bounded. But Conjecture 59.1 is the statement; the damped oscillation is the mechanism. Following the lesson of Papers 53–56, mechanism parameters are not confused with the theorem target.

The oscillation unifies four observables: R_wt oscillation (Table 1), cross-product sign oscillation (§3.1), B⁰ sign changes (§3.2), and z/√j peak and decline (Paper 57).


§5. BL mechanism: exponential baseline, not antisymmetric cancellation

5.1. Falsification of antisymmetric cancellation

Paper 58 hypothesized that B^{(1)} = Σ h(p)/p · (log p − c_j) is small due to cancellation between left (log p < c_j) and right (log p > c_j) halves. The cancellation ratio |B^{(1)}| / max(|B^{(1)}_L|, |B^{(1)}_R|) at j ≥ 26 is 0.72–0.97, meaning essentially no cancellation. Yet 2^j · (B^{(1)})² < 0.07 everywhere.

5.2. The true mechanism

The iid baseline 2^j · Var_iid := 2^j · Σ(x_r · dlp_r)² decreases monotonically from 0.0011 (j=14) to 0.0005 (j=32), approximately O(1/j). This is the dominant effect: each individual contribution x_r · dlp_r decays as 1/p ≈ 2^{-j}, and 2^j times the sum of their squares yields O(1/j) from prime counting.

The excess ratio (B^{(1)})²/Var_iid peaks at 112 (j=27) but stays sub-exponential (likely oscillatory, tracking the R_wt cycle). Polynomial amplification cannot overcome exponential baseline decay.

5.3. Two-layer baseline

Unconditional (coarse): 2^j · Σ(x_r · dlp_r)² ≤ C · j (from Guy + Chebyshev).

Conditional (sharp): 2^j · Σ(x_r · dlp_r)² ≤ C / j (if D_j ≈ σ²/(j·2^j), empirically confirmed).

The sharp bound motivates Conjecture 59.2 but is not in the closure chain.


§6. Conjecture 59.2: Spectral Derivative Bound

6.1. Statement

Conjecture 59.2. For all sufficiently large j:

sup_{|t| ≤ 1} |E_j(t)|² / t² ≤ C_j · 2^{-j}, where log C_j = o(j).

6.2. Relation to Paper 58

Paper 58's Conjecture 58.2 (2^j · (B^{(1)})² ≤ C) controls the leading Taylor coefficient. Conjecture 59.2 strengthens this to uniform-in-t control on |t| ≤ 1, as required by Paper 50's BL_α definition.

6.3. Empirical support

Leading-order: 2^j · (B^{(1)})² has maximum 0.069 (j=27) across 19 j-values. Exact E_j(t) at t = 0.1, 0.3, 1.0 confirms 2^j · |E_j(t)|²/t² < 0.06 for |t| ≤ 1 at all tested blocks.


§7. Complete closure chain

7.1. Conjecture 59.1 → DSF_α for all α > 0

Proof. By 59.1: B_j² ≤ C · j · D_j. By Guy's bound and Chebyshev (unconditional): D_j ≤ C' · j / 2^j. Combining: B_j² ≤ C'' · j² / 2^j. Therefore DSF_α = Σ (1+j)^{1+2α} |B_j|² ≤ Σ j^{3+2α} / 2^j < ∞ for all α > 0. □

7.2. Conjecture 59.2 → BL_α for all α < 1

Proof. From 59.2: |E_j(t)| ≤ √C_j · 2^{-j/2} · |t| for |t| ≤ 1. For α < 1: sup_{|t|≤1} |E_j(t)|/|t|^α ≤ √C_j · 2^{-j/2}. Since log C_j = o(j), the sum Σ √C_j · 2^{-j/2} converges. □

7.3. Assembly

SD is unconditional (Paper 50 Prop 4.1). DSF_α + BL_α → Hölder (Paper 50 Thm 6.2). Hölder + SD → A_h converges (Paper 50 Prop 6.3, Karamata). A_h → D(s) boundary (Paper 50 Prop 6.4). Prime power layer analytic (Paper 50 Prop 7.1, unconditional). → H'.

Conj 59.1 + Guy + Chebyshev → DSF_α ∀α > 0
Conj 59.2 → BL_α ∀α < 1
SD (unconditional)
  → Hölder → A_h converges → D(s) boundary + P(s) analytic → H'

Input: 59.1 + 59.2 + SD. Output: H'. Hidden assumptions: None.


§8. Role reassignment

Paper Final role
50 Foundation: SD, DSF_α/BL_α definitions, chain Steps 4–8
51 Foundation: spectral target, WN rate, gap quantification
52 Alternative route (backup); Thm 3.1 superseded
53 Mechanism: screened long memory
54 Mechanism: power-law autocorrelation
55 Core mechanism: damped oscillation
56 Statement origin: R_wt = O(1) first identified
57 Conditional bridge (subsumed by 59.1)
58 Refinement: 58.2 → 59.2; 58.1 killed
59 Statement: canonical conjectures, complete chain

§9. Conclusion

The distance from H' is exactly two conjectures:

Conjecture 59.1 (R_wt = O(1)): supported by 19 j-values in [0.79, 25.3].

Conjecture 59.2 (spectral derivative bound): supported by 19 j-values with 2^j·(B¹)² < 0.07.

The closure chain 59.1 + 59.2 + SD → H' has no hidden assumptions. Conjecture 59.2 is closer to provable. Conjecture 59.1 encapsulates the deep arithmetic of IC recursion.
