Current Formal Status. Within the canonical formal corpus, exactly 4 Lean theorem declarations have achieved machine-verified closure in module
Fabrica.FQFTunder Lean 4.16.0 (0sorry, 0admit):thm_resolvent_two_sided_inverse,thm_first_resolvent_identity_algebraic,thm_shifted_operator_difference, andthm_first_resolvent_identity_exact. The former provisional axiomFQFT_closurehas been discharged and de-quarantined by constructive inductive scale closure (0 quarantined axioms). This verifies discrete fiber resolvent identities; it does not constitute machine verification of FQFT as a complete physical field theory.
Public Status Boundary. Fractal Quantum Field Theory (FQFT) is the multiscale field-theoretic framework developed within the Science of Fabric Reality (SFR), classified as
MATHEMATICAL_ARCHITECTURE_CONVERGED_V1withFULL_PHYSICAL_FQFT_OPEN(Gate Ω287-G7-R3 Adjudicated). It investigates whether ultraviolet (UV) divergences and infrared (IR) scaling behaviors of quantum field theories on multiscale substrates can be systematically formulated through closed symmetric Dirichlet forms and their associated self-adjoint generators on metric-measure spaces. Continuous interacting field theory and prospective laboratory tests remain open ( ACTIVE_P4_SEALS = 0).
1. The Core Physical and Mathematical Problem
Conventional Quantum Field Theory (QFT) relies on a continuous, four-dimensional pseudo-Riemannian spacetime manifold
- Ultraviolet Singularities: Loop integrals over continuous four-momentum
diverge at high energies, requiring perturbative subtraction schemes (dimensional regularization, counterterms). - Dimension Conflation: Continuum physics assumes a single dimension (
). On multiscale, fractal, or network substrates, at least four distinct dimensions diverge and must be disambiguated: where is the Hausdorff dimension, is the spectral dimension (governing heat kernel decay), is the walk dimension (governing diffusion), and is the topological dimension. - Fermion Family Origin: The Standard Model accommodates three fermion generations via empirical Yukawa coupling matrices without deriving the generation count or mass hierarchy from geometric first principles.
FQFT models field dynamics through the spectral properties of multiscale Dirichlet spaces to investigate whether generation counts and mass ratios can emerge from discrete spectral bounds.
2. Structural Layer Stratification: R0, R1, and R26
To prevent confusion between abstract mathematics and specific lattice realization candidates, FQFT is partitioned into three distinct formal layers:
┌─────────────────────────────────────────────────────────────────────────────┐

3.3 Machine-Verified Resolvent Theorems (Fabrica.FQFT)
Four formal theorems establishing the algebraic structure of discrete fiber resolvents and shifted operators have achieved machine verification in Lean 4:
| Theorem Declaration | Mathematical Content | Verification Status |
|---|---|---|
thm_resolvent_two_sided_inverse | Invertible operator pair identity: | MACHINE_VERIFIED (Lean 4.16.0) |
thm_first_resolvent_identity_algebraic | Algebraic first resolvent identity: | MACHINE_VERIFIED (Lean 4.16.0) |
thm_shifted_operator_difference | Shifted operator difference evaluation: | MACHINE_VERIFIED (Lean 4.16.0) |
thm_first_resolvent_identity_exact | Exact first resolvent identity on analytic resolvent data: | MACHINE_VERIFIED (Lean 4.16.0) |
Axiomatic Discharge Note. The provisional statement
FQFT_closure() has been formally discharged and de-quarantined via machine-verified inductive scale closure, establishing zero quarantined axioms across the formal library.
4. FQFT-R1: Spectral Realization & Mass Calibration
In the discrete candidate realization FQFT-R1, the field resides on a 5-regular graph candidate network
4.1 Adjacency vs. Laplacian Spectra & Bounded Support
- Full Bounded Spectrum: On any finite or infinite 5-regular graph
, the adjacency spectrum satisfies . Consequently, the shifted combinatorial Laplacian has full spectrum bounded by: - Kesten–McKay Continuous Bulk: On the infinite 5-regular tree
, the asymptotic spectrum forms a continuous bulk supported on with Kesten–McKay density: Under , this shifts the continuous bulk strictly to: - Fractal Status Demarcation: The fractal status of
is strictly NOT_ESTABLISHED. A regular graph is a discrete combinatorial 1-complex, not a self-similar metric-measure fractal space. The dimension firewall () remains strictly enforced.
