[严格正控制] self-matching triangular-site:有限 rank-source 对称、near-critical 方程与 square-site universality 对照 #776

Description

@LightChainr

为什么这是当前最重要的 control 之一

#773 已把 square-site rank law 写成 canonical coordinates

b = 1/2 log(P0/P2)        matching-odd,
c = P1/[2 sqrt(P0P2)]     matching-even,

并提出 near-critical two-variable rank-source equation、Fisher L^-1/2、conditional-K cumulant parity ladder和 self-normalized curve c=C(b)

Square-site 的困难是 primal NN 与 matching NN+NNN 是两个不同 microscopic graphs,因此 finite-size b,c 不具备 exact self-dual parity;raw M'' 还能混入 thermal-coordinate curvature。

Triangular-site 是理想正控制:matching lattice 与原 lattice 相同,pc=1/2,critical/near-critical scaling 与 arm exponents有严格理论。 若 finite torus digital-Alexander identity按预期成立,则 complement 本身给一个全尺寸 exact symmetry,而不是 asymptotic universality 猜想。

Phase A — finite exact theorem,先证明再算

选定一个 honest periodic triangular-lattice site torus convention(明确 vertices/edges/faces;小 L 不得折叠本应不同的局部邻边)。证明或给精确最小例外:

r(omega) + r(omega^c) = 2

with the same triangular connectivity on both colours。

若成立,则立即有

P2_L(p)=P0_L(1-p),
P1_L(p)=P1_L(1-p),
M_L(p)=-M_L(1-p).

因此对每个 honest L:

p_L^* = 1/2 exactly,
b_L(1/2+eps) = -b_L(1/2-eps),
c_L(1/2+eps) =  c_L(1/2-eps).

在 logit z=0:

g(z)=log(P2/P0) is exactly odd,
all g_(2m)(0)=0,
(log c)_(2m+1)(0)=0.

这是一套非常强的 pipeline regression;如果 finite code 不满足,先修 geometry/convention,不做 scaling fit。

Phase B — exact small sizes

用两个独立路径至少做到 honest L=3,4,最好 transfer 扩到 L=5..8(按资源)。保存

C[L,j,k] = # configs with rank j and K=k,

并逐 k 验证 binomial sum。

在 p=1/2 报告:

a_L=P0=P2,
c_L=(1-2a_L)/(2a_L),
rank-source zero angle theta_L=acos(-c_L),
conditional K cumulants n=1..6,
Fisher rho_KX,
self-normalized curve curvature d2 log c/db2.

所有 even derivative zero 必须在 exact arithmetic 下为0,不只是浮点小。

Phase C — rigorous near-critical interface

主检索/证明问题:把 Garban–Pete–Schramm triangular-site near-critical scaling limit接到 periodic torus rank events。

需要明确:

  1. torus/periodic domain 在 quad-crossing framework 中的实现或可引用扩展;
  2. rank-0/1/2 events 是否为 scaling-limit continuity events;
  3. thermal lambda convention和 complement symmetry lambda -> -lambda
  4. 从而得到
Pi2(lambda;tau)=Pi0(-lambda;tau),
Pi1(lambda;tau)=Pi1(-lambda;tau),
Z_tau(lambda,s)=Z_tau(-lambda,-s)

作为 triangular-site 的 rigorously grounded control。

若 torus extension 文献没有现成 theorem,写出最小缺失 lemma;不要把 planar GPS 自动宣称成 torus theorem。

Phase D — square vs triangular 的 parameter-free universality test

最优先比较 self-normalized curve

c = C_L(b)

而不是先对齐 p 或 thermal metric。

Triangular finite curves exact even;square/matching pair only asymptotically应靠近同一个 continuum C_*(b;tau)(若 universality正确)。比较:

c(0),
d log c/db |0   (triangular exact 0),
d2 log c/db2 |0,
whole small-|b| curve.

这是真正的跨格点 topological equation-of-state test:所有 thermal reparameterisation 都已被 b 消掉。

第二层再比较需要 metric 的量:

g1/L^(3/4),
rho_KX^2 sqrt(L),
metric-free g3/g1^3,
conditional-density CLT.

为什么它能区分 square-site 的 M'' 解释

triangular self-matching 使 g_2=Delta Var(K)=0 at z=0 exactly。因此:

  • 若 square-site g2~L^(3/4) 主要来自 microscopic thermal-coordinate curvature / matching asymmetry,这是合理;
  • 若某解释宣称该 even derivative 是一个 unavoidable universal even primary amplitude,它必须解释为什么 self-matching triangular control identically kills it。

这比只看 square-site 两个 slope 更有判别力。

外部理论优先级

  • Smirnov critical triangular site;
  • Smirnov–Werner arm exponents;
  • Garban–Pete–Schramm pivotal/near-critical scaling;
  • torus/compact-surface extensions if present;
  • Pinson/Newman–Ziff critical wrapping probabilities as continuum topology anchor。

区分 theorem / extension / universality conjecture。

Stop rules

  • 若 finite triangular digital-Alexander identity 在选定 convention 失败,先报告具体 obstruction,不换 convention 偷救;
  • 不用 triangular exact symmetry“证明”square L^-4;
  • 不从 L<=8 fit 新 exponent;
  • 不把 self-normalized curve 等同 CFT field identification;
  • 不改 original-U contract。
