Abstract

We perform microscopic anatomy of the Ω=2 layer (semi-primes n=pq), discovering that the H' criterion reduces precisely to a prime-core harmonic average problem.

An h₀-free gap formula is established: G(n) = ρ(p) + ρ(q) − ρ(n−1) + 1; j(n)>0 iff G(n)<0. Independent confirmation: γ₂ = 0.453 (R² = 0.996). G is integer-valued, concentrated on {−1, 0, +1, +2} (87%).

A prime penalty is discovered: primes q have systematically higher ρ(q) than the local mean (E[R(p)] ≈ 4.57 vs E[R(n)] ≈ 2.76), because primes are pure additive injection points in the DP recursion. This explains E[diff] = 1.83 for n=2q (far below h₀·ln 2 = 2.48).

Discrete locking of n=2q: diff = ρ(2q−1) − ρ(q) concentrates on {1, 2, 3} (92%). P(j>0) = P(diff≥3) ≈ 0.211, frozen across five decades. In the currently visible range, p=2 is the only prime-core family showing no clear downward trend.

A prime-core profile is established for 95 primes (p=2 to 499): cp = P(j>0|n=pq). cp is primarily determined by margin = E[diff] − threshold (Corr = 0.917). Margin oscillation is driven by the discrete deviation of ρ(p) from h₀·ln p — and ρ(p) deviation is strongly correlated with the smoothness of p−1 (Corr(ln P⁺(p−1), cp) = −0.714). Smooth p−1 → low ρ(p) → high margin → high cp. Rough p−1 → high ρ(p) → low margin → low cp.

Key new finding: except for p=2, nearly all cp(N) for p ≥ 3 decline across decades (2–15%/decade) — cp is not a constant but an N-dependent slowly decaying quantity. At fixed N=10⁸, the partial harmonic average H(P;N) = Σ cp/p ÷ Σ 1/p decreases from 0.35 to 0.27 (P=499) — declining in the P direction but far from zero.

H' criterion for Ω=2 is: does the harmonic Cesàro average c̄h(N) → 0? Current data cannot determine this — whether cp decay is genuine asymptotic behavior or finite-scale effect remains open.

30 fixed-core families in Ω=3 (m=6, 10, 14, …, 95) exhibit the same margin-driven structure. Fixed-core locking is universal across all Ω layers.

Paper XXXI's γk is a mixture effect of fixed-core families. Model A's finite-scale "victory" reflects the decay phase of the mixture.

Keywords: additive complexity, prime penalty, discrete locking, prime-core profile, harmonic Cesàro average, fixed-core family, integer complexity

1. Introduction

1.1 Background

Paper XXXI established the layer-by-layer bottleneck map for H', extracted γk, and proposed the effective index Γ = λ·γk criterion. But γk was found to be a mixture effect. This paper performs microscopic anatomy of the simplest Ω=2 layer, revealing the internal structure of that mixture.

1.2 Contributions

(A) h₀-free gap formula and γ₂ confirmation (§2). (B) Prime penalty (§3). (C) n=2q discrete locking (§4). (D) 95-prime core profile (§5). (E) ρ(p) deviation ↔ p−1 smoothness correlation (§5). (F) cp(N) per-decade decay (§6). (G) Harmonic Cesàro average as H' criterion (§7). (H) Ω=3 fixed-core structure (§8).

2. h₀-Free Gap Formula and γ₂ Confirmation

2.1 Formula

For n = pq (p = P⁻(n), canonical core), define:

$$G(n) = \rho(p) + \rho(q) - \rho(n-1) + 1$$

Then j(n) > 0 if and only if G(n) < 0. No h₀ appears.

2.2 Discreteness of G

G is integer-valued. Distribution at [10⁷, 10⁸):

G−10+1+2Other
Share18.5%30.1%24.2%14.4%12.8%

Four values account for 87%. Median = 0, mean = +0.53.

2.3 γ₂ Independent Confirmation

$$q_2(N) \sim 0.877\cdot(\ln N)^{-0.453}, \quad R^2 = 0.996$$

14 points (N = 10³ to 10⁸). Confirms Paper XXXI's γ₂ = 0.449.

2.4 Rapid Decay of Balanced Semi-Primes

The Ω=2 layer is not homogeneous. Restricting to "balanced" semi-primes (q/p < 10) reveals strikingly different behavior.

Theory: for pq ≈ √n, ρ(p) + ρ(q) ≈ h₀·ln n ≈ ρ(n−1), giving G ≈ +1 (structural positive bias).

Data ([10⁷, 10⁸)): E[G] = +1.23, P(j>0) = 0.107. Fitting:

$$q_2^{\text{bal}}(N) \sim 3.03\cdot(\ln N)^{-1.14}, \quad R^2 = 0.992$$

γbal = 1.14 — 2.5× faster than the overall γ₂ = 0.45. This directly proves γ₂ is a mixture of fast-decaying balanced subfamilies and slowly-decaying/frozen unbalanced subfamilies.

3. Prime Penalty

Block 3b data (N = 10⁸):

CategoryE[R(·)]
General integers n ∈ [10⁷, 10⁸)2.76
Primes p ∈ [10⁷, 10⁸)4.57

Prime penalty: gap ≈ 1.8. Primes are pure additive injection points: ρ(p) = ρ(p−1) + 1, never compressed by multiplication. Hence ρ(p) is systematically elevated relative to its logarithmic scale.

For n=2q: E[diff₂] ≈ h₀·ln 2 − Δ₂ ≈ 2.48 − 0.65 ≈ 1.83, where Δ₂ ≈ 0.65 is the family-specific prime-conditioned correction for p=2 (distinct from the unconditional gap of ~1.8).

4. Discrete Locking of n=2q

4.1 Threshold

Since ρ(2) = 1: G = 2 + ρ(q) − ρ(2q−1). Thus j>0 iff diff ≥ 3.

4.2 diff Distribution

[10⁷, 10⁸), 2.65 million primes q:

diff+1+2+3Other
Share21.6%49.5%21.1%7.8%

Three values account for 92%. P(j>0) = P(diff≥3) ≈ 21.1%.

4.3 Five Decades of Confirmed Freezing

DecadeE[diff]P(j>0)
[10³, 10⁴)1.8430.195
[10⁵, 10⁶)1.8400.209
[10⁷, 10⁸)1.8290.211

P(j>0) ≈ 0.211 is frozen across five decades. In the currently visible range, p=2 is the only prime-core family in Ω=2 without a clear downward trend.

5. Prime-Core Profile

5.1 Definition

For each prime p, canonical decomposition n = pq (qp prime, p = P⁻(n)):

$$c_p(N) = P(j>0 \mid n=pq,\; pq \leq N)$$ $$\text{threshold}_p = \rho(p)+1, \quad \text{margin}_p = E[\text{diff}_p] - \text{threshold}_p$$

When q=p (prime squares), these are asymptotically negligible (<0.01%) and excluded.

5.2 95-Prime Profile (Selected)

At N = 10⁸:

pρ(p)thrE[diff]margincpP⁺(p−1)p−1

193181919.41+0.410.4713192=2⁶·3

cp range: [0.005, 0.543]. Full 95-point profile computed.

5.3 Margin Dominance

Corr(margin, cp) = +0.917. Margin is the primary driver; local discrete distribution contributes second-order variation.

5.4 ρ(p) Deviation Driven by p−1 Smoothness

Corr(ln P⁺(p−1), ρ(p)/h₀ ln p) = +0.683.

Corr(ln P⁺(p−1), cp) = −0.714.

Correlation-supported explanation chain: smooth p−1 → low ρ(p−1) → low ρ(p) → low threshold → high margin → high cp. Rough p−1 → reverse.

Extreme cases: p=193 (p−1=192=2⁶·3, P⁺=3) → cp=0.471. p=179 (p−1=178=2·89, P⁺=89) → cp=0.005.

5.5 No Monotone Drift in Current Range

ρ(p)/(h₀·ln p) oscillates between 0.95–1.13 for p ≤ 499. No systematic drift supporting a monotone scissors picture. Since P⁺(p−1) is known to oscillate indefinitely, cp is unlikely to trend to zero via a simple "h₀·ln p outgrows ρ(p)" mechanism — but the harmonic average may still decline through subtler distributional effects.

6. Per-Decade Decay of cp(N)

pcp(10³)cp(10⁵)cp(10⁷)Trend
20.1950.2090.211frozen
30.5580.5510.542slow decline
50.5450.4860.470clear decline
70.2670.2390.223clear decline
1090.4650.4300.377fast decline
1930.6420.5210.467fast decline

Except p=2, nearly all cp(N) for p ≥ 3 are declining. Rates range from 2%/decade (p=3) to 15%/decade (p=193). cp(N) is not a fixed arithmetic constant — it is an N-dependent slowly decaying quantity. Current data cannot distinguish "cp → constant > 0" from "cp → 0 very slowly."

7. Harmonic Cesàro Average as H' Criterion

7.1 Canonical Decomposition

Each Ω=2 composite n=pq (p=P⁻(n), q=P⁺(n), qp) maps uniquely to prime-core p. Prime squares (q=p) contribute <0.01% and are negligible. On squarefree semiprimes:

$$q_2^{(\text{sqf})}(N) = \sum_{p} w_p(N)\cdot c_p(N)$$

where wp(N) ≈ (1/p) / Σ(1/ℓ) asymptotically. Since prime squares contribute O(π(√N)/#Ω=2) → 0, q₂ and \(q_2^{(\text{sqf})}\) have the same asymptotics.

7.2 Correct Criterion

q₂ → 0 if and only if the harmonic Cesàro average tends to zero:

$$\bar{c}_h(N) := \frac{\displaystyle\sum_{p \leq \sqrt{N}} c_p(N)/p}{\displaystyle\sum_{p \leq \sqrt{N}} 1/p} \to 0$$

This is not equivalent to "Σ cp/p converges" (which is only sufficient). If cp(N) ~ C/ln ln p, the series diverges yet c̄h → 0.

7.3 Partial Profile at Fixed N

H(P;N) at fixed N=10⁸ as function of truncation P:

PH(P; N)
100.351
500.305
1000.291
2000.281
5000.270

H declines from 0.35 to 0.27. This is the profile shape at fixed N — not the asymptotic c̄h(N) vs N. The true H' criterion requires understanding the joint profile (p, N) ↦ cp(N).

7.4 H' Implications

(i) If cp(N) are true constants → c̄h stable at ~0.27 → H' fails at Ω=2.

(ii) If cp(N) for p≥3 have genuine asymptotic decay → c̄h(N) → 0 → H' holds at Ω=2.

§6 data favor scenario (ii) but decay rates are too small to confirm. H' status at Ω=2 remains open.

7.5 Partial Validation

Block 7b: Σ wp·cp (p ≤ 23) = 0.174. Actual q₂ = 0.232. Coverage 54%, ratio = 0.75. Weighted sum direction is correct — contributions from p > 23 should close the gap.

8. Ω=3 Fixed-Core Structure

8.1 Framework

For Ω=3 layer, canonical core m (Ω(m)=2, squarefree), n = mq (q = P⁺(n)):

$$G_m(q) = \rho(m) + \rho(q) - \rho(mq-1) + 1, \quad j>0 \;\text{iff}\; \text{diff}_m \geq \rho(m)+2$$

Note: current scope covers only squarefree cores m = pp₂. Squareful families (n=p²q) not yet included.

8.2 30-Core Profile (Selected)

At N = 10⁸:

mFactorsρ(m)thrE[diff]margincm
62·3566.37+0.370.457
102·5788.25+0.250.395
142·79109.41−0.590.166

777·11161715.90−1.100.082
822·41151616.23+0.230.401

Same margin-driven structure. cm range [0.063, 0.645]. Fixed-core locking is universal across Ω layers. Paper XXXI's γk is a mixture of fast-decaying balanced subfamilies + slowly-decaying prime-core subfamilies + weight drift.

9. Corrections to Paper XXXI

γk is a mixture effect. Model A's finite-scale "victory" reflects the decay phase of the mixture — fast-decaying subfamilies dominate at current scales. Asymptotically, once these clear, the residual floor emerges — but that floor may itself be slowly decaying (§6), so Model B (qk → constant) is also not guaranteed. True behavior may lie between the two: extremely slow decay.

10. Discussion

10.1 Core Contributions

Nine findings: (1) h₀-free formula + γ₂ confirmation. (2) Prime penalty Δ₂. (3) n=2q discrete locking. (4) 95-prime profile. (5) ρ(p) ↔ P⁺(p−1) smoothness correlation. (6) cp(N) per-decade decay. (7) Harmonic Cesàro criterion. (8) Ω=3 fixed-core universality. (9) γk mixture reinterpretation.

10.2 Open Problems

(1) Is cp(N) decay genuine asymptotic behavior or finite-scale effect? (2) c̄h(N) → 0 or → c̄ > 0? — the ultimate Ω=2 criterion. (3) Higher-Ω fixed-core profiles. (4) Analytic proof of n=2q locking via local limit law. (5) ρ(p) per-prime fluctuations and deep arithmetic structure.

Fixed-Core 锁定与 Prime-Core Profile——H' 的残余底板结构

摘要

我们对 Ω=2 层(半素数 n=pq)进行微观解剖,发现 H' 的判据可以精确归结为一个 prime-core harmonic 平均问题。

建立 h₀-free gap 公式:G(n) = ρ(p) + ρ(q) − ρ(n−1) + 1。j(n)>0 当且仅当 G(n)<0。独立确认 γ₂ = 0.453(R² = 0.996)。G 是整数值,集中在 {−1, 0, +1, +2}(占 87%)。

发现素数惩罚:素数 q 的 ρ(q) 系统性高于局部均值(E[R(p)] ≈ 4.57 vs E[R(n)] ≈ 2.76),因为素数是 DP 中的纯 additive 注入点。这解释了 n=2q 的 E[diff] = 1.83(远低于 h₀·ln 2 = 2.48)。

发现 n=2q离散锁定:diff = ρ(2q−1) − ρ(q) 集中在 {1, 2, 3}(占 92%)。P(j>0) = P(diff≥3) ≈ 0.211,五个 decade 完全冻结。在当前可见尺度上,p=2 是 Ω=2 层中唯一没有显示明确下行趋势的 prime-core family。

建立 prime-core profile:对 95 个素数(p=2 到 499),测量 cp = P(j>0|n=pq)。cp 主要由 margin = E[diff] − threshold 决定(Corr = 0.917)。margin 的振荡由 ρ(p) 相对于 h₀·ln p 的离散偏差驱动——而 ρ(p) 的偏差由 p−1 的平滑度决定(Corr(ln P⁺(p−1), cp) = −0.714)。p−1 平滑 → ρ(p) 低 → margin 高 → cp 高。p−1 粗糙 → ρ(p) 高 → margin 低 → cp 低。

关键的新发现:除 p=2 外,几乎所有 p ≥ 3 的 cp(N) 都在逐 decade 下降(2–15%/decade)——cp 不是常数,是 N-dependent 的缓慢衰减量。固定 N=10⁸ 下的 partial harmonic 平均 H(P;N) = Σ cp/p ÷ Σ 1/p 从 0.35 缓慢下降到 0.27(P=499)——在 P 方向下降但远未趋零。

H' 在 Ω=2 层的判据精确化为:harmonic Cesàro 平均 c̄h(N) → 0?当前数据无法判定——cp 的衰减是真实的渐近行为还是有限尺度效应。

Ω=3 层的 30 个 squarefree fixed-core(m=6, 10, 14, …, 95)展示相同的 margin 驱动结构,强烈支持 fixed-core 锁定是更普遍的现象。

Paper XXXI 的 γk 是 fixed-core families 的混合效应。Model A 在有限尺度上的"胜出"反映的是混合的衰减阶段。

§1 引言

1.1 背景

Paper XXXI 建立了 H' 的逐层瓶颈地图,提取了 γk 并提出了有效指数 Γ = λ·γk 判据。但 γk 被发现是混合效应。本文对最简单的 Ω=2 层进行微观解剖,揭示混合的内部结构。

1.2 本文贡献

(A) h₀-free gap 公式与 γ₂ 独立确认(§2)。(B) 素数惩罚的发现与量化(§3)。(C) n=2q 离散锁定机制(§4)。(D) 95 个素数的 prime-core profile(§5)。(E) ρ(p) 偏差与 p−1 平滑度的强相关(§5)。(F) cp(N) 的逐 decade 衰减——非冻结常数(§6)。(G) Harmonic Cesàro 平均作为 H' 判据(§7)。(H) Ω=3 层的 fixed-core 结构(§8)。

§2 h₀-Free Gap 公式与 γ₂ 确认

2.1 公式

对半素数 n = pqpq),约定 p = P⁻(n)(最小素因子)作为规范 core:

$$G(n) = \rho(p) + \rho(q) - \rho(n-1) + 1$$

j(n) > 0 当且仅当 G(n) < 0。不涉及 h₀。

2.2 G 的离散性

数值观察 1。 G 是整数值。在 [10⁷, 10⁸):

G−10+1+2其余

四个值占 87%。中位数 = 0,均值 = +0.53。

2.3 γ₂ 独立确认

$$q_2(N) \sim 0.877\cdot(\ln N)^{-0.453}, \quad R^2 = 0.996$$

14 个点(N = 10³ 到 10⁸)。与 Paper XXXI 的 γ₂ = 0.449 吻合。

2.4 平衡半素数的快速衰减

Ω=2 层并非单一群体。限定 q/p < 10 的"平衡半素数"(pq 量级相近)呈现完全不同的行为。

理论:对 pq ≈ √n,ρ(p) + ρ(q) ≈ 2h₀·ln(√n) = h₀·ln n ≈ ρ(n−1),因此 G(n) ≈ +1——结构性正值。

[10⁷, 10⁸) 的平衡半素数:E[G] = +1.23, P(j>0) = 0.107。

$$q_2^{\text{bal}}(N) \sim 3.03\cdot(\ln N)^{-1.14}, \quad R^2 = 0.992$$

γbal = 1.14——比整层的 γ₂ = 0.45 快 2.5 倍。这直接证明 γ₂ 是快速衰减的平衡子群与缓慢衰减/冻结的不平衡子群的混合物。

§3 素数惩罚

Block 3b 数据(N = 10⁸):

类别E[R(·)]
一般整数 n ∈ [10⁷, 10⁸)2.76
素数 p ∈ [10⁷, 10⁸)4.57

素数惩罚:差距 ≈ 1.8。素数是 DP 中的纯 additive 注入点:ρ(p) = ρ(p−1) + 1。素数不经过乘法压缩——而合数有多条乘法路径可以压缩 ρ。因此素数的 ρ 相对于其对数尺度偏高。

n=2q:E[diff₂] ≈ h₀·ln 2 − Δ₂ ≈ 2.48 − 0.65 ≈ 1.83,其中 Δ₂ ≈ 0.65 是 p=2 family 的 prime-conditioned 修正(进入 diff 公式时的净效应),不同于 §3 的无条件差距 1.8。

§4 n=2q 的离散锁定

因为 ρ(2) = 1:G = 2 + ρ(q) − ρ(2q−1)。故 j>0 当且仅当 diff ≥ 3。

对每个素数 p,规范分解 n = pqqp 素数,p = P⁻(n)),定义:

$$c_p(N) = P(j>0 \mid n=pq,\; pq \leq N)$$ $$\text{threshold}_p = \rho(p)+1, \quad \text{margin}_p = E[\text{diff}_p] - \text{threshold}_p$$

q=pn=p²——这些 prime square 渐近 negligible(<0.01%),排除。

5.3 cp 由 Margin 主导

Corr(margin, cp) = +0.917。 margin 是第一主导变量。局部离散分布的宽度和偏斜贡献二阶修正。

5.4 ρ(p) 的偏差由 p−1 的平滑度驱动

数值观察 4。

Corr(ln P⁺(p−1), ρ(p)/h₀ ln p) = +0.683

Corr(ln P⁺(p−1), cp) = −0.714

高相关支持的解释链(非严格因果证明):p−1 平滑 → ρ(p−1) 低 → ρ(p) = ρ(p−1)+1 低 → threshold 低 → margin 高 → cp 高。p−1 粗糙 → 反向。

极端案例:p=193(p−1=192=2⁶·3,P⁺=3)→ cp=0.471。p=179(p−1=178=2·89,P⁺=89)→ cp=0.005。

5.5 当前范围内无 Monotone Drift

在当前可见范围内(p ≤ 499),ρ(p)/(h₀·ln p) 在 0.95–1.13 之间振荡。没有观察到支持 monotone scissors picture 的系统性 drift。由于 p−1 的最大素因子在解析数论中已知不收敛,cp 不太可能因简单的"h₀·ln p 远超 ρ(p)"机制而系统性趋零——但不能排除 cp 的 harmonic 平均因更精细的分布效应而缓慢下降。

p=2 冻结外,几乎所有 p ≥ 3 的 cp(N) 都在下降。下降率从 2%/decade(p=3)到 15%/decade(p=193)不等。cp(N) 不是精确的算术常数——是 N-dependent 的缓慢衰减量。当前数据无法区分"cp → 常数 > 0"和"cp → 0 极慢"。这是 H' 的核心悬念。

§7 H' 的 Harmonic Cesàro 平均判据

7.1 Ω=2 层的规范分解

每个 Ω=2 合数 n=pqp=P⁻(n), q=P⁺(n), qp)唯一对应一个 prime-core p。Prime squares(n=p²)贡献 <0.01%,渐近 negligible。排除后,在 squarefree semiprimes 上:

$$q_2^{(\text{sqf})}(N) = \sum_{p} w_p(N)\cdot c_p(N)$$

其中 wp(N) ≈ (1/p)/Σ(1/ℓ) 渐近。由于 prime squares 的贡献 → 0,q₂(N) 与 \(q_2^{(\text{sqf})}(N)\) 渐近行为相同。

7.2 Harmonic Cesàro 平均

q₂ → 0 的正确判据是 harmonic Cesàro 平均趋零:

$$\bar{c}_h(N) := \frac{\displaystyle\sum_{p \leq \sqrt{N}} c_p(N)/p}{\displaystyle\sum_{p \leq \sqrt{N}} 1/p} \to 0$$

这不等价于"Σ cp/p 收敛"——后者只是充分条件。如果 cp(N) ~ C/ln ln p,Σ cp/p 仍然发散但 c̄h → 0。

7.3 固定 N 下的 Partial Profile

数值观察 6。 H(P;N) 随截断上限 P 的变化(固定 N=10⁸):

PH(P; N)
100.351
500.305
1000.291
2000.281
5000.270

H 从 0.35 缓慢下降到 0.27。这是在固定 N 下将更多 prime-core 纳入时 profile 的形状——不是 c̄h(N) 随 N 的渐近行为。真正的 H' 判据需要理解联合 profile (p, N) ↦ cp(N) 的全局行为。

7.4 对 H' 的意义——两变量问题

h(N) 同时依赖于(a)每个固定 p 的 cp(N) 是否随 N 衰减,和(b)截断上限 √N 扩大时新纳入的大 p 的 cp 值。

§6 数据:几乎所有 p ≥ 3 的 cp(N) 在逐 decade 下降(N 方向有利)。§7.3 数据:H(P; 10⁸) 随 P 也在下降(P 方向有利)。但衰减率都太小,无法确认是渐近真实还是有限尺度效应。

当前数据无法判定 H' 在 Ω=2 的真伪。这是一个关于 DP 递推深层结构的开放问题。

7.5 加权和部分验证

Block 7b:Σ wp·cp (p ≤ 23) = 0.174。实际 q₂ = 0.232。覆盖 54%,比值 = 0.75。加权和方向正确——p > 23 的贡献补上后应接近闭合。

§8 Ω=3 层的 Fixed-Core 结构

8.1 框架

对 Ω=3 层,规范 core m(Ω(m)=2,squarefree),n = mqq = P⁺(n)):

$$G_m(q) = \rho(m) + \rho(q) - \rho(mq-1) + 1, \quad j>0 \;\text{当且仅当}\; \text{diff}_m \geq \rho(m)+2$$

注意:当前只覆盖 squarefree core m = pp₂。squareful families(如 n=p²q)未纳入——渐近上 squarefree 占主导,但完整分解需要进一步工作。

8.2 30 个 Core 的 Profile(选录)

数值观察 7。 N = 10⁸:

m因子ρ(m)thrE[diff]margincm
62·3566.37+0.370.457
102·5788.25+0.250.395
142·79109.41−0.590.166
153·5899.92+0.920.645
222·11111211.14−0.860.110
393·13121313.51+0.510.508
777·11161715.90−1.100.082
822·41151616.23+0.230.401

同样的 margin 驱动结构。cm 范围 [0.063, 0.645]。Fixed-core 锁定是更普遍的现象。Paper XXXI 的 γk 是快速衰减子群 + 缓慢衰减 prime-core + 权重漂移三种叠加效应的观察。

§9 对 Paper XXXI 的修正

9.1 γk 是混合效应

Paper XXXI 的 γk 是 fixed-core families 的有效叠加指数。真正的本征量是每个 family 的 cm(N) 和权重 wm(N)。

9.2 Model A vs Model B

Paper XXXI 的 Model A(qk ~ (ln N)−γk)在有限尺度上的"胜出"反映了混合的衰减阶段——快衰减子群主导。渐近地,一旦快衰减清零,底板暴露——但底板本身可能也在缓慢衰减(§6),所以 Model B(qk → 常数 > 0)也不一定最终胜出。真实行为可能是介于两者之间的极慢衰减。

§10 讨论

10.1 核心贡献

(1) h₀-free gap 公式 + γ₂ = 0.453 独立确认。(2) 素数惩罚与 family-specific Δ₂ 的发现——解释 E[diff₂] = 1.83。(3) n=2q 离散锁定(c₂ ≈ 0.211 冻结)。(4) 95 个素数的 prime-core profile:cp 由 margin 主导(Corr = 0.917)。(5) ρ(p) 偏差 ↔ P⁺(p−1) 平滑度的强相关(Corr = −0.714)。(6) cp(N) 对 p≥3 的逐 decade 衰减——非冻结常数。(7) H' 判据:harmonic Cesàro 平均 c̄h(N) → 0?(8) Ω=3 的 30 个 core 展示同样的 margin 驱动结构。(9) Paper XXXI 的 γk 是混合效应。

10.2 开放问题

(1) cp(N) 的衰减是否是真实的渐近行为?还是有限尺度效应?(2) c̄h(N) → 0 还是 c̄h(N) → c̄ > 0?——H' 在 Ω=2 的最终判据。(3) 更高 Ω 层的 fixed-core profile 是否有类似结构和衰减?(4) n=2q 的冻结是否可以从 diff 的整数值局部极限定理解析证明?(5) ρ(p) 的逐素数波动——是否与 Artin 猜想或其他深层算术结构有联系?
