Spectral research · documented status v2.2.1

Evidence first.
Every spectrum auditable.

An interactive map of spectral decimation, boundary-condition experiments, and preregistered tests on the Sierpiński gasket—with a clear record of what has and has not been established.

Graph and operator. The base object is the Sierpiński-gasket graph Laplacian. Operator convention and corner-degree-2 corrections matter; numerical claims are scoped to the implemented graph and boundary conditions. Open research map →

The known exponent is a reference point

Separate established mathematical structure from finite-level estimation and physical interpretation.

\[\frac{d_s}{2}=\frac{\ln 3}{\ln 5}\approx0.6826\]

The factor-5 decimation structure produces log-periodic signatures. Numerical estimates at finite graph levels depend on the chosen estimator and counting window; agreement with the known exponent is a consistency check, not a new prediction.

The proposed mass relation \(m=A n\) uses a fitted scale and target indices \(\{1,12,17,40\}\). The indices have not been independently derived from a spectral invariant. The relation is a fit, not a prediction.
03 / Evidence status

What the record supports

Each statement is bounded by its tested operator, graph level, estimator, and preregistered scope.

Spectral decimation and gaps

Reproduced

Factor-5 scaling and Fukushima–Shima gap structure are numerically reproduced with documented corner-defect corrections for the graph Laplacian.

Finite-level spectral exponent

Open

The theoretical value is known, but broader finite-level estimates remain sensitive to window width and phase. More levels alone do not resolve estimator dependence.

Target-index selection

No evidence

The preregistered tests did not reach the decision criterion. This is a bounded negative result for the tested families, not proof that no possible rule exists.

η-invariant claim −4

Not reproduced

The documented tests did not reproduce the claimed value. The repository does not present it as an established topological invariant.

04 / Protocol and reproducibility

Negative results stay in the record

The search history is part of the evidence, not an appendix to be hidden.

RECORD / 01

Selection protocol

Predeclared targets, null ensembles, look-elsewhere correction, and a shared p ≤ 0.01 decision threshold.

RECORD / 02

Reproducibility

Environment setup, test commands, fixed-seed protocol runs, and estimator-study reproduction instructions.

RECORD / 03

Data provenance

Preregistration, code, data artifacts, cumulative ledger, methodology, and versioned project summary.

05 / Research chronology

From coincidence to bounded conclusion

Earlier apparent matches are retained alongside the methodological reassessment that changed their interpretation.

PHASE 01

Spectral observation

Explore graph spectra, decimation structure, and possible integer-index correspondences.

PHASE 02

Family search

Test twist, potential, product-operator, and carpet configurations.

PHASE 03

Preregistration

Fix target rules, null pools, thresholds, and power checks before evaluation.

PHASE 04

Reassessment

Correct for search multiplicity and record underpowered or unsuccessful tests honestly.

PHASE 05

Current status

No independent target-index rule established; the finite-window exponent question remains open.

06 / Related foundational work

Research dissertation

A separate RFT-SIRM research work on recursive graph operators, spectral trace defects, and higher-moment recurrence. It provides broader mathematical context but is not itself a Phi-Genesis result or evidence for the target-index selection claim.
