Abstract

We close the B-bound, the first open input in the proof landscape of $D(N) \to 1$ to be resolved unconditionally. Two theorems are proved. Theorem (Prime-Power Second Moment). For each fixed $k \geq 2$, $E[\varepsilon_{P^-(n)}(n)^2 \mid \Omega(n) = k, n \leq N] \to 0$ as $N \to \infty$. The proof uses only three inputs: the pointwise bounds $\varepsilon_p(a) \leq 2$ (multiplicative) and $|\varepsilon_p(a)| \ll_k \ln p$ (from $\rho_E = O(\ln n)$), the Landau formula for $N_k(x)$, and the constraint $p^k \leq N$ on the support. Theorem (Unconditional B-bound). For each fixed $k \geq 2$, $\mathrm{Var}(B \mid \Omega = k, n \leq N) = O_k(1)$ uniformly in $N$. This follows immediately from the Prime-Power Second Moment Theorem and the B-bound Reduction of Paper 19. Numerical data confirm: $E[\varepsilon_{P^-}^2 \mid \Omega = 8] = 1.84$ and $E[\varepsilon_{P^-}^2 \mid \Omega = 12] = 1.98$ at $N = 10^7$, far below any divergence threshold. A complete atlas of $\varepsilon_p(2)$ for $p \leq 10^4$ shows the distribution concentrated in $[-2, 2]$ with sparse negative outliers ($|\varepsilon_p(2)| \geq 4$ for only 2.8% of primes). For fixed small primes ($p = 2, 3, 5, 7$), $\varepsilon_p(a) \in \{0, 1, 2\}$ for all $a \leq 20$ with rigid periodic patterns and no growth. The DP self-correction mechanism is further quantified: large jumps compress not only the conditional mean (95% regression, Paper 19) but also the conditional variance ($\mathrm{Var}(G(n+1) \mid j(n) \geq 3) = 0.126$ vs. unconditional $1.23$, a 90% compression). $\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$ on the $\Omega = 8$ shell, supporting the view that the $O(1)$ variance of $G$ arises from cancellation of shared DP history rather than coprimality-based independence. The proof landscape is updated: B-bound is the first node to move from (N) to (T); the Local Lipschitz property remains the most leveraged open target.

§1. Introduction

§1.1. Context

Paper 19 (DOI: 10.5281/zenodo.19026991) proved the B-bound Reduction: $\mathrm{Var}(B) = O_k(1)$ follows from $E[\varepsilon_{P^-}^2 \mid \Omega = k] < \infty$. The present paper closes this last step, proving the prime-power second moment is not merely bounded but tends to zero.

§1.2. Notation

As in Papers 17–19. $\varepsilon_p(a) = \rho_E(p^a) - \rho_E(p^{a-1}) - \rho_E(p)$ for $a \geq 2$. $N_k(x) = \#\{n \leq x : \Omega(n) = k\}$. $M_{k,N}(p, a) = \#\{n \leq N : \Omega(n) = k, P^-(n) = p, v_{P^-}(n) = a\}$.


§2. Pointwise Bounds on $\varepsilon_p(a)$

§2.1. Upper Bound

Proposition (Multiplicative Upper Bound). For all primes $p$ and $a \geq 2$, $\varepsilon_p(a) \leq 2$.

Proof. $p^a = p \cdot p^{a-1}$ is a valid split, so $\rho_E(p^a) \leq \rho_E(p) + \rho_E(p^{a-1}) + 2$. $\square$

§2.2. Lower Bound

Proposition (Logarithmic Lower Bound). For each fixed $a$, $|\varepsilon_p(a)| \ll_a \ln p$.

Proof. $\rho_E(m) = O(\ln m)$ (Paper 11 [5]). So $|\varepsilon_p(a)| \leq \rho_E(p^a) + \rho_E(p^{a-1}) + \rho_E(p) \leq C_a \ln p$. $\square$

§2.3. Structural Recursion

The DP for prime powers gives:

$$\rho_E(p^a) = \min\left(\rho_E(p^a - 1) + 1,\ \min_{1 \leq i \leq a-1}(\rho_E(p^i) + \rho_E(p^{a-i}) + 2)\right)$$

Setting $S_p(a) = \rho_E(p^a - 1) + 1 - \rho_E(p^{a-1}) - \rho_E(p)$:

$$\varepsilon_p(a) \geq \min(S_p(a),\ \varepsilon_p(2),\ \ldots,\ \varepsilon_p(a-1),\ 2)$$

Consequence. New deep-negative values of $\varepsilon_p(a)$ can only arise from the successor route (when $p^a - 1$ has anomalously low complexity), not from multiplicative splits. This is consistent with Paper 17's observation that $\varepsilon_p(2) < 0$ occurs when $p^2 - 1 = (p-1)(p+1)$ has an unusually favorable factorization.

§3. The Prime-Power Second Moment Theorem

§3.1. Statement

Theorem (Prime-Power Second Moment). For each fixed $k \geq 2$:

$$E[\varepsilon_{P^-(n)}(n)^2 \mid \Omega(n) = k, n \leq N] \to 0 \quad (N \to \infty).$$

In particular, for $k \geq 3$:

$$E[\varepsilon_{P^-}^2 \mid \Omega = k, n \leq N] \ll_k (\ln\ln N)^{-2}.$$

For $k = 2$, the bound is $O(N^{-1/2} \ln^3 N)$ (Case B dominates).

§3.2. Proof

Write

$$E[\varepsilon_{P^-}^2 \mid \Omega = k] = \frac{1}{N_k(N)} \sum_{a=2}^{k} \sum_p M_{k,N}(p,a) \cdot \varepsilon_p(a)^2.$$

Case A: $2 \leq a \leq k-1$.

If $M_{k,N}(p, a) \neq 0$, then $n = p^a m$ with $\Omega(m) = k - a$ and $P^-(m) > p$, so $n \geq p^a \cdot p^{k-a} = p^k$, giving $p \leq N^{1/k}$.

By the Landau upper bound (Tenenbaum [7], Ch. II.6): for each fixed $r \geq 1$,

$$N_r(x) \ll_r \frac{x (\ln\ln x)^{r-1}}{\ln x} \quad (x \geq x_0(r)).$$

Since $p \leq N^{1/k}$, we have $N/p^a \geq N^{1-a/k} \geq N^{1/k}$, so the Landau upper bound applies to $N_{k-a}(N/p^a)$:

$$\frac{M_{k,N}(p,a)}{N_k(N)} \leq \frac{N_{k-a}(N/p^a)}{N_k(N)} \ll_k \frac{1}{p^a (\ln\ln N)^a}.$$

Combined with $\varepsilon_p(a)^2 \ll_k (\ln p)^2$:

$$\sum_p \frac{M_{k,N}(p,a)}{N_k(N)} \cdot \varepsilon_p(a)^2 \ll_k \frac{1}{(\ln\ln N)^a} \sum_p \frac{(\ln p)^2}{p^a}.$$

Since $a \geq 2$, the series $\sum_p (\ln p)^2 / p^a$ converges. So this contribution is $O_k((\ln\ln N)^{-a})$.

Case B: $a = k$.

Then $n = p^k$, so $M_{k,N}(p, k) \leq 1$ for each $p$, and $p \leq N^{1/k}$.

$$\frac{1}{N_k(N)} \sum_{p \leq N^{1/k}} \varepsilon_p(k)^2 \ll_k \frac{N^{1/k} \ln^2 N}{N (\ln\ln N)^{k-1} / \ln N} = N^{1/k - 1} \cdot \frac{\ln^3 N}{(\ln\ln N)^{k-1}} \to 0.$$

Combining Cases A and B: The dominant term is $a = 2$, giving

$$E[\varepsilon_{P^-}^2 \mid \Omega = k] \ll_k (\ln\ln N)^{-2} \to 0. \quad \square$$

§3.3. Remark on the Regime Distinction

The theorem holds for fixed $k$, $N \to \infty$. In the "tight-support" regime of Paper 19 ($k$ large relative to $\ln\ln N$, where $v_{P^-} \geq 2$ dominates), $E[\varepsilon_{P^-}^2]$ is numerically $\approx 1.9$ at $N = 10^7$. These are different asymptotic regimes: the theorem describes the fixed-$k$ limit where $v \geq 2$ events become rare; the numerical data describe the high-$k$ regime where they are common but individually benign. Both are consistent with $\mathrm{Var}(B) = O_k(1)$.

§4. The Unconditional B-bound

§4.1. Statement and Proof

Theorem (Unconditional B-bound). For each fixed $k \geq 2$:

$$\mathrm{Var}(B \mid \Omega = k, n \leq N) = O_k(1)$$

uniformly in $N$.

Proof. By Paper 19 Proposition (B-bound Reduction): $\mathrm{Var}(B) \leq 2\mathrm{Var}(R_k) + 2\mathrm{Var}(E_k)$, where $\mathrm{Var}(R_k) \leq (2k-2)^2$ (fixed $k$) and $\mathrm{Var}(E_k) \leq E[\varepsilon_{P^-}^2]$. By the Prime-Power Second Moment Theorem, $E[\varepsilon_{P^-}^2] \ll_k 1$. $\square$

§4.2. Significance

This is the first open input in the proof landscape of $D(N) \to 1$ to be closed unconditionally. In the dependency graph of Paper 19 §8.3, B-bound moves from (N) to (T).

1229 primes total. The distribution is centered near 0 with a slight positive skew. The negative tail is sparse: $|\varepsilon_p(2)| \geq 4$ accounts for only 34 primes (2.8%).

All values in $\{0, 1, 2\}$. No growth with $a$. Rigid periodic patterns: $\varepsilon_2(a)$ alternates $0, 2$; $\varepsilon_3(a) = \varepsilon_5(a) = 2$ always; $\varepsilon_7(a) = 1$ when $4 \mid a$, else $2$. (Selected rows shown; full table for $a = 2, \ldots, 20$ available in supplementary data.)

§5.3. Shell-Averaged Second Moment

$k$Shell size$E[\varepsilon_{P^-}^2 \mid \Omega = k]$
8207,2071.840
1211,0681.978

Conditioned on $v_{P^-} \geq 2$: $E[\varepsilon_{P^-}^2 \mid v \geq 2] \approx 1.99$ for both $k$. The shell-averaged value is pulled below 2 by the $v = 1$ contribution (which is zero).


§6. Variance Compression After Large Jumps

§6.1. Conditional Distribution of $G(n+1)$

On the $\Omega = 8$ shell at $N = 10^7$ (all $n \leq 10^7$ with $\Omega(n) = 8$, conditioning on $j(n) \geq 3$ and examining the next integer $n+1$):

$G(n+1)$Frequency
089.92%
18.92%
21.10%
30.06%

$\mathrm{Var}(G(n+1) \mid j(n) \geq 3) = 0.126$ vs. unconditional $\mathrm{Var}(G) = 1.23$. A 90% variance compression.

Interpretation. The self-correction mechanism (Paper 19 §5) is stronger than previously described: large jumps not only regress the conditional mean (95%) but also compress the conditional variance (90%). After a large jump, $G(n+1)$ is nearly deterministically zero.

§6.2. $\mathrm{Corr}(M_n, M_{n+1})$

On the $\Omega = 8$ shell (425 consecutive pairs where both $n$ and $n+1$ have $\Omega = 8$):

$$\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$$

This is essentially equal to $\mathrm{Corr}(\rho_E(n), \rho_E(n-1)) = 0.9676$ (Paper 19 §6).

Interpretation. $M_n$ and $M_{n+1}$ are NOT approximately independent despite $\gcd(n, n+1) = 1$. Both track the global DP level ($\approx c^* \ln n$), and their 97% correlation is what produces the $O(1)$ variance of $G = S - M$ through cancellation — not coprimality-based independence.

§6.3. Conditional Variance by $G(n)$

Among the 425 consecutive pairs where both $n$ and $n+1$ have $\Omega = 8$ (same sample as §6.2):

$G(n)$Sample size$\mathrm{Var}(G(n+1) \mid G(n))$
0111.17
1500.78
21500.73
31450.60
4580.65

The conditional variance decreases moderately with $G(n)$ (from 1.17 at $g = 0$ to 0.60 at $g = 3$), then stabilizes. At no point does it exceed the unconditional variance ($\approx 1.23$). The small sample size at $g = 0$ ($n = 11$) limits the reliability of that data point.


§7. The Updated Proof Landscape

§7.1. What M10 Establishes

Theorems (proved):

  • Prime-Power Second Moment: $E[\varepsilon_{P^-}^2 \mid \Omega = k] \to 0$ ($N \to \infty$)
  • Unconditional B-bound: $\mathrm{Var}(B \mid \Omega = k) = O_k(1)$

Numerical discoveries:

  • $\varepsilon_p(2)$ atlas: concentrated in $[-2, 2]$, sparse outliers
  • $\varepsilon_p(a)$ for small $p$: rigid $\{0, 1, 2\}$ patterns, no growth
  • Shell-averaged $E[\varepsilon_{P^-}^2] \approx 1.9$
  • Variance compression: 90% after large jumps
  • $\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$: shared DP history, not independence

Correction to Paper 19 §5:

  • Self-correction is both mean regression AND variance compression
  • $M_n$-$M_{n+1}$ correlation is $\approx 0.97$ (high), not $\approx 0$ (independent)

A.1. Four-AI Contributions to M10

ChatGPT proved the Prime-Power Second Moment Theorem (§3), using Landau formula asymptotics and the pointwise $\varepsilon_p$ bounds. ChatGPT also computed the complete $\varepsilon_p(2)$ atlas ($p \leq 10^4$ via DP to $10^8$), the high-$a$ table for small primes, and the shell-averaged second moments — serving as the primary theoretical and computational engine for M10.

Grok computed the self-correction variance compression (§6.1: $\mathrm{Var}(G(n+1) \mid j \geq 3) = 0.126$), the $M_n$-$M_{n+1}$ correlation (§6.2: 0.9663), and the conditional variance by $G(n)$ (§6.3).

Claude analyzed the three formalization frameworks for Local Lipschitz, identified that Framework 2 ($M_n$-$M_{n+1}$ independence) is incorrect (the high correlation 0.9663 confirms shared DP history rather than independence), and derived the heuristic bound $|\varepsilon_p(a)| = O(\sqrt{\ln p})$ which motivated the exact proof.

Gemini was unable to complete assigned computations in M10 due to session stability issues. Gemini's M8 discovery of the anti-correlation engine remains foundational.

A.2. Role of the Thermodynamic Interface

The thermodynamic perspective contributed the observation that B-bound closure corresponds to establishing that "splitting costs are locally bounded" — a natural property in thermodynamic systems where the activation energy for phase transitions does not grow with system size. The variance compression (§6.1) further strengthens the fluctuation-dissipation analogy: not only does the system restore equilibrium after large perturbations, it does so with reduced fluctuations, analogous to critical damping.

关闭 B-bound:素数幂二阶矩定理与第一个无条件闭合节点

摘要

本文关闭 B-bound,这是 $D(N) \to 1$ 证明格局中第一个被无条件解决的开放输入。证明了两个定理。定理(素数幂二阶矩)。对每个固定 $k \geq 2$,$E[\varepsilon_{P^-(n)}(n)^2 \mid \Omega(n) = k, n \leq N] \to 0$($N \to \infty$)。证明仅使用三个输入:逐点界 $\varepsilon_p(a) \leq 2$(乘法界)和 $|\varepsilon_p(a)| \ll_k \ln p$(来自 $\rho_E = O(\ln n)$),$N_k(x)$ 的 Landau 公式,以及支撑约束 $p^k \leq N$。定理(无条件 B-bound)。对每个固定 $k \geq 2$,$\mathrm{Var}(B \mid \Omega = k, n \leq N) = O_k(1)$ 关于 $N$ 一致。此结果直接由素数幂二阶矩定理和论文 19 的 B-bound 归约推出。数值确认:$N = 10^7$ 下 $E[\varepsilon_{P^-}^2 \mid \Omega = 8] = 1.84$,$E[\varepsilon_{P^-}^2 \mid \Omega = 12] = 1.98$,远低于任何发散阈值。$p \leq 10^4$ 的 $\varepsilon_p(2)$ 完整图谱显示分布集中于 $[-2, 2]$,稀疏负异常值($|\varepsilon_p(2)| \geq 4$ 仅占 2.8% 的素数)。对固定小素数($p = 2, 3, 5, 7$),$\varepsilon_p(a) \in \{0, 1, 2\}$ 对所有 $a \leq 20$ 成立,呈刚性周期模式,无增长。DP 自纠正机制进一步量化:大跳跃不仅压缩条件均值(95% 回归,论文 19),还压缩条件方差($\mathrm{Var}(G(n+1) \mid j(n) \geq 3) = 0.126$,无条件 1.23,90% 压缩)。$\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$($\Omega = 8$ 壳),支持以下观点:$G$ 的 $O(1)$ 方差来自共享 DP 历史的对消,而非互素性导致的独立性。证明格局更新:B-bound 是第一个从 (N) 移至 (T) 的节点;局部 Lipschitz 性质仍为最有杠杆的开放目标。

§1. 引言

§1.1. 背景

论文 19(DOI: 10.5281/zenodo.19026991)证明了 B-bound 归约:$\mathrm{Var}(B) = O_k(1)$ 由 $E[\varepsilon_{P^-}^2 \mid \Omega = k] < \infty$ 推出。本文关闭最后一步,证明素数幂二阶矩不仅有界,而且趋于零。

§1.2. 记号

同论文 17–19。$\varepsilon_p(a) = \rho_E(p^a) - \rho_E(p^{a-1}) - \rho_E(p)$($a \geq 2$)。$N_k(x) = \#\{n \leq x : \Omega(n) = k\}$。$M_{k,N}(p, a) = \#\{n \leq N : \Omega(n) = k, P^-(n) = p, v_{P^-}(n) = a\}$。


§2. $\varepsilon_p(a)$ 的逐点界

§2.1. 上界

命题(乘法上界)。对所有素数 $p$ 和 $a \geq 2$,$\varepsilon_p(a) \leq 2$。

证明。$p^a = p \cdot p^{a-1}$ 是合法分裂,故 $\rho_E(p^a) \leq \rho_E(p) + \rho_E(p^{a-1}) + 2$。$\square$

§2.2. 下界

命题(对数下界)。对每个固定 $a$,$|\varepsilon_p(a)| \ll_a \ln p$。

证明。$\rho_E(m) = O(\ln m)$(论文 11 [5])。故 $|\varepsilon_p(a)| \leq \rho_E(p^a) + \rho_E(p^{a-1}) + \rho_E(p) \leq C_a \ln p$。$\square$

§2.3. 结构递推

素数幂的 DP 给出:

$$\rho_E(p^a) = \min\left(\rho_E(p^a - 1) + 1,\ \min_{1 \leq i \leq a-1}(\rho_E(p^i) + \rho_E(p^{a-i}) + 2)\right)$$

设 $S_p(a) = \rho_E(p^a - 1) + 1 - \rho_E(p^{a-1}) - \rho_E(p)$:

$$\varepsilon_p(a) \geq \min(S_p(a),\ \varepsilon_p(2),\ \ldots,\ \varepsilon_p(a-1),\ 2)$$

推论。$\varepsilon_p(a)$ 的新深负值只能来自后继路线($p^a - 1$ 复杂度异常低时),不能来自乘法分裂。这与论文 17 的观察一致:$\varepsilon_p(2) < 0$ 发生在 $p^2 - 1 = (p-1)(p+1)$ 有异常有利因子分解时。

§3. 素数幂二阶矩定理

§3.1. 陈述

定理(素数幂二阶矩)。对每个固定 $k \geq 2$:

$$E[\varepsilon_{P^-(n)}(n)^2 \mid \Omega(n) = k, n \leq N] \to 0 \quad (N \to \infty).$$

特别地,对 $k \geq 3$:

$$E[\varepsilon_{P^-}^2 \mid \Omega = k, n \leq N] \ll_k (\ln\ln N)^{-2}.$$

对 $k = 2$,界为 $O(N^{-1/2} \ln^3 N)$(情形 B 主导)。

§3.2. 证明

$$E[\varepsilon_{P^-}^2 \mid \Omega = k] = \frac{1}{N_k(N)} \sum_{a=2}^{k} \sum_p M_{k,N}(p,a) \cdot \varepsilon_p(a)^2.$$

情形 A:$2 \leq a \leq k-1$。

若 $M_{k,N}(p, a) \neq 0$,则 $n = p^a m$,$\Omega(m) = k - a$,$P^-(m) > p$,故 $n \geq p^a \cdot p^{k-a} = p^k$,给出 $p \leq N^{1/k}$。

由 Landau 上界(Tenenbaum [7],第 II.6 章):对每个固定 $r \geq 1$,

$$N_r(x) \ll_r \frac{x (\ln\ln x)^{r-1}}{\ln x} \quad (x \geq x_0(r)).$$

由 $p \leq N^{1/k}$ 得 $N/p^a \geq N^{1-a/k} \geq N^{1/k}$,故 Landau 上界适用于 $N_{k-a}(N/p^a)$:

$$\frac{M_{k,N}(p,a)}{N_k(N)} \leq \frac{N_{k-a}(N/p^a)}{N_k(N)} \ll_k \frac{1}{p^a (\ln\ln N)^a}.$$

结合 $\varepsilon_p(a)^2 \ll_k (\ln p)^2$:

$$\sum_p \frac{M_{k,N}(p,a)}{N_k(N)} \cdot \varepsilon_p(a)^2 \ll_k \frac{1}{(\ln\ln N)^a} \sum_p \frac{(\ln p)^2}{p^a}.$$

由 $a \geq 2$,级数 $\sum_p (\ln p)^2 / p^a$ 收敛。故此层贡献为 $O_k((\ln\ln N)^{-a})$。

情形 B:$a = k$。

此时 $n = p^k$,故每个 $p$ 的 $M_{k,N}(p, k) \leq 1$,且 $p \leq N^{1/k}$。

$$\frac{1}{N_k(N)} \sum_{p \leq N^{1/k}} \varepsilon_p(k)^2 \ll_k \frac{N^{1/k} \ln^2 N}{N (\ln\ln N)^{k-1} / \ln N} = N^{1/k - 1} \cdot \frac{\ln^3 N}{(\ln\ln N)^{k-1}} \to 0.$$

合并情形 A 和 B:主项来自 $a = 2$,给出

$$E[\varepsilon_{P^-}^2 \mid \Omega = k] \ll_k (\ln\ln N)^{-2} \to 0. \quad \square$$

§3.3. 关于 Regime 区分的注释

定理在固定 $k$,$N \to \infty$ 下成立。在论文 19 的"紧支撑"regime($k$ 相对于 $\ln\ln N$ 较大,$v_{P^-} \geq 2$ 占主导)中,$N = 10^7$ 下 $E[\varepsilon_{P^-}^2]$ 数值为 $\approx 1.9$。这是不同的渐近 regime:定理描述的是固定 $k$ 极限,其中 $v \geq 2$ 事件变得稀少;数值数据描述的是高 $k$ regime,其中这些事件常见但个别良性。两者与 $\mathrm{Var}(B) = O_k(1)$ 一致。

§4. 无条件 B-Bound

§4.1. 陈述与证明

定理(无条件 B-bound)。对每个固定 $k \geq 2$:

$$\mathrm{Var}(B \mid \Omega = k, n \leq N) = O_k(1)$$

关于 $N$ 一致。

证明。由论文 19 命题(B-bound 归约):$\mathrm{Var}(B) \leq 2\mathrm{Var}(R_k) + 2\mathrm{Var}(E_k)$,其中固定 $k$ 时 $\mathrm{Var}(R_k) \leq (2k-2)^2$,$\mathrm{Var}(E_k) \leq E[\varepsilon_{P^-}^2]$。由素数幂二阶矩定理,$E[\varepsilon_{P^-}^2] \ll_k 1$。$\square$

§4.2. 意义

这是 $D(N) \to 1$ 证明格局中第一个被无条件关闭的开放输入。在论文 19 §8.3 的依赖图中,B-bound 从 (N) 移至 (T)


§5. $\varepsilon_p$ 图谱

§5.1. $\varepsilon_p(2)$ 的分布($p \leq 10^4$)

$\varepsilon_p(2)$计数比例例子
−630.24%1439, 3119, 6299
−550.41%1499, 5749, 6719, 7559, 8699

127021.97%19, 29, 31, ...
219215.62%3, 5, 7, ...

共 1229 个素数。分布以 0 为中心,轻微正偏。负尾稀疏:$|\varepsilon_p(2)| \geq 4$ 仅 34 个素数(2.8%)。

§5.2. 小素数的 $\varepsilon_p(a)$(高 $a$)

$a$$\varepsilon_2(a)$$\varepsilon_3(a)$$\varepsilon_5(a)$$\varepsilon_7(a)$
20222
32222
40221
52222
60222
80221
100222
120221
160221
200221

所有值在 $\{0, 1, 2\}$ 中。随 $a$ 无增长。刚性周期模式:$\varepsilon_2(a)$ 在 0 和 2 间交替;$\varepsilon_3(a) = \varepsilon_5(a) = 2$ 恒定;$\varepsilon_7(a) = 1$ 当 $4 \mid a$,否则为 2。(展示部分行;$a = 2, \ldots, 20$ 的完整表见补充数据。)

§5.3. 壳平均二阶矩

$k$壳大小$E[\varepsilon_{P^-}^2 \mid \Omega = k]$
8207,2071.840
1211,0681.978

在 $v_{P^-} \geq 2$ 条件下:$E[\varepsilon_{P^-}^2 \mid v \geq 2] \approx 1.99$(两个 $k$)。壳平均值被 $v = 1$ 贡献(为零)拉至 2 以下。


§6. 大跳跃后的方差压缩

§6.1. $G(n+1)$ 的条件分布

$\Omega = 8$ 壳,$N = 10^7$(所有 $n \leq 10^7$ 且 $\Omega(n) = 8$,条件于 $j(n) \geq 3$,检查下一个整数 $n+1$):

$G(n+1)$频率
089.92%
18.92%
21.10%
30.06%

$\mathrm{Var}(G(n+1) \mid j(n) \geq 3) = 0.126$,无条件 $\mathrm{Var}(G) = 1.23$。90% 方差压缩。

解释。自纠正机制(论文 19 §5)比先前描述的更强:大跳跃不仅回归条件均值(95%),还压缩条件方差(90%)。大跳跃后,$G(n+1)$ 近乎确定性地等于零。

§6.2. $\mathrm{Corr}(M_n, M_{n+1})$

$\Omega = 8$ 壳上(425 对连续整数,两者均有 $\Omega = 8$):

$$\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$$

这与 $\mathrm{Corr}(\rho_E(n), \rho_E(n-1)) = 0.9676$(论文 19 §6)基本相同。

解释。尽管 $\gcd(n, n+1) = 1$,$M_n$ 和 $M_{n+1}$ 并非近似独立。两者都跟踪全局 DP 水平($\approx c^* \ln n$),其 97% 相关性通过对消产生 $G = S - M$ 的 $O(1)$ 方差——而非互素性导致的独立性。

§6.3. 按 $G(n)$ 的条件方差

在 425 对连续整数中(两者均有 $\Omega = 8$,与 §6.2 相同样本):

$G(n)$样本量$\mathrm{Var}(G(n+1) \mid G(n))$
0111.17
1500.78
21500.73
31450.60
4580.65

条件方差随 $G(n)$ 适度递减(从 $g = 0$ 的 1.17 到 $g = 3$ 的 0.60),然后稳定。始终未超过无条件方差($\approx 1.23$)。$g = 0$ 处样本量($n = 11$)较小,限制了该数据点的可靠性。


§7. 更新后的证明格局

§7.1. M10 确立的内容

定理(已证):

  • 素数幂二阶矩:$E[\varepsilon_{P^-}^2 \mid \Omega = k] \to 0$($N \to \infty$)
  • 无条件 B-bound:$\mathrm{Var}(B \mid \Omega = k) = O_k(1)$

数值发现:

  • $\varepsilon_p(2)$ 图谱:集中于 $[-2, 2]$,稀疏异常值
  • 小 $p$ 的 $\varepsilon_p(a)$:刚性 $\{0, 1, 2\}$ 模式,无增长
  • 壳平均 $E[\varepsilon_{P^-}^2] \approx 1.9$
  • 方差压缩:大跳跃后 90%
  • $\mathrm{Corr}(M_n, M_{n+1}) = 0.9663$:共享 DP 历史,非独立性

对论文 19 §5 的修正:

  • 自纠正既是均值回归也是方差压缩
  • $M_n$-$M_{n+1}$ 相关 $\approx 0.97$(高),非 $\approx 0$(独立)

§7.2. $D(N) \to 1$ 的更新开放输入

输入状态变化
B-bound(T) 已关闭M10:第一个无条件闭合
$\sigma(G) = O(1)$局部 Lipschitz(N,开放)自纠正 + 方差压缩作为机制
Scale term 单调性数值不变
固定 $k$ 的 I-a开放不变
Lemma II数值良性不变
SPF-正性收敛数值(下游)不变

§7.3. 证明依赖图(更新版)

局部 Lipschitz (N) ⟶ Var(A) = O(1) Var(B) = O_k(1) [T, 已关闭 — 论文 20] Var(A) = O(1) (待局部 Lipschitz) + Var(B) = O_k(1) (T) ⟶ Var(G_spf) = O_k(1) Var(G_spf) = O_k(1) + 命题 C (T) + Scale 单调性 (N) ⟶ I-b I-b + I-a (T 高-k / N 固定-k) ⟶ Lemma I Lemma I + Lemma II (N) + B-bound (T) ⟶ Thm 5(论文 16, T) Thm 5 + SPF-正性收敛 (N) + Sathe-Selberg (T) ⟶ D(N) → 1

A.1. 四 AI 对 M10 的贡献

ChatGPT 证明了素数幂二阶矩定理(§3),使用 Landau 公式渐近和逐点 $\varepsilon_p$ 界。ChatGPT 还计算了完整的 $\varepsilon_p(2)$ 图谱($p \leq 10^4$,DP 到 $10^8$),小素数的高 $a$ 表,以及壳平均二阶矩——是 M10 的主要理论和计算引擎。

Grok 计算了自纠正方差压缩(§6.1:$\mathrm{Var}(G(n+1) \mid j \geq 3) = 0.126$),$M_n$-$M_{n+1}$ 相关(§6.2:0.9663),以及按 $G(n)$ 的条件方差(§6.3)。

Claude 分析了局部 Lipschitz 的三个形式化框架,识别出框架 2($M_n$-$M_{n+1}$ 独立性)不正确(高相关 0.9663 确认了共享 DP 历史而非独立性),并推导了启发式界 $|\varepsilon_p(a)| = O(\sqrt{\ln p})$,为精确证明提供了动机。

Gemini 因会话稳定性问题未能完成 M10 的指定计算。Gemini 在 M8 中发现的反相关引擎仍为基础性结果。

A.2. 热力学接口的角色

热力学视角贡献了以下观察:B-bound 的关闭对应于确立"分裂成本局部有界"——在热力学系统中,相变的激活能不随系统大小增长是自然性质。方差压缩(§6.1)进一步加强了涨落-耗散类比:系统不仅在大扰动后恢复平衡,还以减少的涨落这样做,类似于临界阻尼。
