[理论/过程] dynamical topological rank:谱样本、torus continuity 与 universal mean-clock autocorrelation #783

Description

@LightChainr

背景

Draft #773 新增了 rank observable X=r-1 的 exact p-biased Fourier / dynamical representation:

C_X(t)/Var X
 = sum_{S!=empty} |Xhat(S)|^2 e^(-t|S|)/Var X
 = E[e^(-t K_spec)],

其中 K_spec 是以 |Xhat(S)|^2 加权的 spectral-sample size。

Exact finite identity:

E[(K_spec)_m]
 = (pq)^m/Var(X)
   * sum_{i1,...,im distinct}
       E[(Delta_i1 ... Delta_im X)^2].

所以 spectral sample 是 multi-pivotal 平方能量的 generating object,不受 signed thermal derivative cancellation 影响。

Matching pair 还有精确 parity:

Xhat_Ghat,q(S)=(-1)^(|S|+1) Xhat_G,p(S),

因此整个 spectral-size law matching-even;self-matching triangular 在 p=1/2 的所有 even Fourier levels 精确为0。

当前小尺寸控制

在各自 finite balance:

E K_spec / L^(3/4):
  square L3 0.7131360, L4 0.7083898
  triangular L3 0.7373186, L4 0.7195889

mean-normalized autocorrelation E exp[-tau K_spec/EK_spec]

tau=1:
  square L3 0.423016, L4 0.443515
  triangular L3 0.435346, L4 0.448147

tau=2:
  square L3 0.207493, L4 0.238291
  triangular L3 0.223579, L4 0.245632

These are exact-configuration / floating Fourier controls, not scaling evidence.

Primary theorem target

For critical triangular-site percolation on periodic tori, use the rigorous dynamical-percolation / pivotal-measure scaling framework to justify a process limit for the topological rank observable.

Desired typed statement:

C_L(t / E K_spec) / Var(X_L)
   -> C_*(t; tau)

for fixed torus modulus tau, or equivalently

K_spec / E K_spec => Y_*(tau)

in the sense justified by the continuum spectral/dynamical process.

Do NOT assume the absolute lattice time metric is universal; mean-clock normalization is part of the target.

Phase A — torus continuity interface

Starting from Garban–Pete–Schramm / Schramm–Smirnov dynamical percolation machinery, determine:

  1. whether periodic torus configurations are covered directly or need a quotient/compact-surface extension;
  2. whether rank-0/1/2 homology events are continuity events in the quad-crossing topology;
  3. whether the rank observable X is sufficiently regular to pass stationary two-time correlations to the scaling limit;
  4. the exact normalization relation between lattice refresh rate and pivotal-measure time.

If any one is absent in the literature, state the minimal missing lemma rather than declaring the theorem.

Phase B — spectral-sample interface

Relate the finite p-biased Fourier spectral sample of X to the continuum pivotal/spectral sample framework.

At minimum show why

E K_spec ~ L^(3/4)

follows from four-arm pivotal scaling for this non-Boolean rank observable (remember Delta_v X can be 2).

Then address whether mean-normalization is sufficient for a lattice-independent law or whether a second microscopic metric survives.

Phase C — exact six-arm correction channel

The finite identity

2 E K_spec/g1 - 1
  = omega_2
  = 2 beta/(alpha+2 beta+gamma)

makes direct 0->2 birth the excess dynamic-clock correction over the static thermal slope.

If #769 finds beta six-arm-like, the prediction is

omega_2 ~ L^-5/3.

This is matching-even and does NOT directly affect the matching-odd L^-4 root hypothesis.

Use #769's real-space pair atlas to check the m=2 identity

E[(K_spec)_2]
  = (pq)^2/VarX * sum_{i!=j} E[(Delta_i Delta_j X)^2].

No duplicate pair enumeration.

Phase D — self-matching parity regression

For triangular site p=1/2, complement oddness of X forces all even Fourier levels to vanish exactly. Any proposed continuum construction should preserve the corresponding odd/even symmetry of the spectral process.

This is a regression, not a field identification.

Literature priority

  • Garban–Pete–Schramm, dynamical/near-critical percolation and pivotal measure;
  • Schramm–Steif / GPS spectral sample and noise sensitivity;
  • any torus/compact-domain extension explicitly covering homology events.

Mark theorem / adaptation / conjecture separately.

Deliverable

with one of:

RIGOROUS_CONTINUUM_INTERFACE,

MISSING_SPECTRAL_SAMPLE_IDENTIFICATION,

不做

  • 不新跑 generic dynamical Monte Carlo;
  • 不用 L3/L4 两点拟合动态 exponent;
  • 不把 matching-even spectral sample叫 matching-odd CFT field;
  • 不修改 STATUS / original-U contract。
