E47 Canonical Spectral Invariants
E47 canonical spectral invariants
Carrier invariant
V = V₂⊗V₂⊗V₂
dim V = 5³ = 125Total Casimir invariant
C = (J₁ + J₂ + J₃)²Casimir spectrum
spec(C) = {0, 2, 6, 12, 20, 30, 42}Isotypic multiplicities
mult = {1, 9, 25, 28, 27, 22, 13}Dimension closure
1 + 9 + 25 + 28 + 27 + 22 + 13 = 125E47 selector
K = (C − 6I)(C − 30I)Kernel invariant
E₄₇ = ker KSpectral decomposition of the kernel
E₄₇ = E₆ ⊕ E₃₀Representation decomposition
E₄₇ ≅ 5V₂ ⊕ 2V₅Kernel dimension
dim E₄₇ = 25 + 22 = 47Complement dimension
125 = 47 + 78Coherence fraction
Ωc = 47/125 = 0.376Orthogonal projector invariant

These are the central exact finite-dimensional invariants repeated across the canonical Notion page, Formalism Registry, machine certificates, and Drive reconstruction corpus.
II. Contraction invariants
Correct positive generator
A = K†K = K²Nonzero spectrum of K²
{11664, 12544, 19600, 32400, 186624}Discrete contraction
Γε = I − εK²Stable step interval
0 < ε < 1/93312Optimal Richardson step
ε* = 1/99144Optimal worst-case contraction factor
ρ* = 15/17Projector limit
limₙ→∞ (I − εK²)ⁿ = P₄₇Continuous contraction
limₜ→∞ e^(−tK²) = P₄₇Slowest continuous off-kernel decay
e^(−11664t)General projector grammar
K → ker K → P → H = I − P → x∞ = Px₀Finite-dimensional completeness
For any orthogonal projector P, choosing K = I − P gives ker K = im P.
The corpus explicitly corrects the earlier signed update I − εK. Because K contains negative eigenvalues, the canonical contraction is through K².

III. 125 → 47 → 5 canonical-core invariants
S₃ permutation invariance
[L,Uσ] = 0
[C,Uσ] = 0
[P₄₇,Uσ] = 0
for σ ∈ S₃Nested carrier chain
ℂ¹²⁵ ⊃ E₄₇ ⊃ EcanDimension chain

Pcan = P₄₇Psym = PsymP₄₇Equivalent spin-2 expression
Pcan = P₆PsymCanonical-core rank
rank(Pcan) = 5Joint spectral–symmetry generator
Acan = K² + 11664(I − Psym)Canonical-core kernel
ker Acan = im Pcan
The Notion canon records this as a separately machine-validated symmetry-resolved refinement of the rank-47 kernel.
IV. Professor’s Cube / C₅³ invariants
Cube carrier
V(C₅ □ C₅ □ C₅) = ℤ₅³
|V| = 125Permutation orthogonality
PᵀP = IQuarter-turn periodicity
P⁴ = IConstant-state preservation
P1 = 1Graph Laplacian
L = LC₅ ⊕ LC₅ ⊕ LC₅Exact Laplacian spectrum
λ(k) = Σⱼ₌₁³ [2 − 2cos(2πkⱼ/5)]Heat-energy monotonicity
E½ = ½ρᵀLρ
˽ = −∥Lρ∥² ≤ 0Graph heat limit
limₙ→∞(I − εL)ⁿ = P₀Constant-mode projector
P₀ = 11ᵀ/125Graph-kernel rank
rank(P₀) = 1E47-kernel rank
rank(P₄₇) = 47Critical inequivalence
P₀ ≠ P₄₇Exact layer-turn Laplacian defect norms
∥PᵀLP − L∥₂ = 2√2
∥PᵀLP − L∥F = 8√3
Thus the Professor’s Cube and E47 share an exact 125-dimensional carrier and S₃ symmetries without conflating their kernels.
V. Discrete Hodge and topology invariants
Discrete Hodge theorem
ker Δq(ε) ≅ Hq(Kε;ℝ)Betti/nullity identity

V ∈ C₀ ⊗ ℝᵈ
WV ∈ C₁Midpoint discrete de Rham map
(WV)([i,j]) = ⟨(vᵢ + vⱼ)/2, xⱼ − xᵢ⟩Rigid translation invariant
harmonic circulation = 0Rigid rotation invariant
rotation maps to a nonzero harmonic circulation around a protected loopAdmissible swarm space
Eswarm = ker Ksafe ∩ W⁻¹(ker Δ₁)Equivalent stacked-kernel form
Eswarm = ker [ Ksafe ; (I − Pharm)W ]
This is the type-correct replacement for multiplying projectors that act on different spaces.

VI. Persistence and safe-motion invariants
Persistence stability
dB(Dq(t),Dq(t′)) ≤ 2vmax|t − t′|Persistence-change bound
|Δpersq| ≤ 4vmax|t − t′|Certified topology dwell time
Δtsafe = (p₀ − τp)/(4vmax)Persistence margin selector
ε* selects the active scale maximizing distance from the persistence interval’s birth/death boundaries.Protected Betti class during dwell
βq(Kε(X(t))) = βqtargetExecution-gate invariant
G = 1 only if all of the following hold simultaneously:
pers ≥ τp
λβ+1(Δq) ≥ τλ
dmin ≥ dsafe
∥KsafeV∥ ≤ τK
β = βtargetFailure closure
Violation of any gate predicate ⇒ fallback / no certified execution.Topology versus clearance distinction
(p₀ − τp)/(4vmax) protects persistence.
(dmin − dsafe)/(2vmax) protects pairwise clearance.
They are different invariants.
The reconciled cross-repository certificate reports the corrected persistence theorem and the type-correct Hodge gate.
VII. Babylonian / Newton invariants
VAT 8389 affine system
x + y = 1800
(2/3)x − (1/2)y = 500Exact solution
(x,y) = (1200,600)Residual invariant
Mx − b = (0,0)Midpoint/correction decomposition
h = 900
z = 300
x = h + z = 1200
y = h − z = 600Babylonian/Newton map
Fₐ(x) = ½(x + a/x)Fixed-point kernel form
Kₐ(x) = x − Fₐ(x)Positive kernel
ker Kₐ = {x > 0 : x² = a}Quadratic error recursion
eₙ₊₁ = eₙ²/(2xₙ)Residual gate
|xₙ² − a| < τRational coherence relation
125x = 47aUnique Newton/coherence compatibility point
a = (125/47)²
The historical Babylonian material supports affine solving, bookkeeping continuity, and iterative arithmetic. The modern E47 spectral machinery remains a separate mathematical construction.

VIII. Coupled Newton–Mean invariants
Fixed-point difference invariant
ρ² − σ² = a − bProduct coordinate
p* = ρσProduct quadratic
(1 − κ²)p² − κ(a + b)p − ab = 0Jacobian spectrum
spec(J*) = {0, τ}Nonzero Jacobian eigenvalue
τ = κ(a + b)/(2p*) + κ²Corrected local-stability domain
−κc(a,b) < κ < 1
These replace the superseded claim that stability holds automatically for every |κ| < 1.
IX. Quantum-information invariants
Noiseless multiplicity spaces
E₄₇ ≅ V₂⊗ℂ⁵ ⊕ V₅⊗ℂ²
with multiplicity sectors ℂ⁵ and ℂ² protected against the stated collective-SU(2) operator algebra.Selective projector channel
ΦP(X) = PXP
is completely positive and trace-nonincreasing.Projector-map fixed-space dimension
dim Fix(ΦP) = 47² = 2209K² semigroup operation
X ↦ e^(−tK²) X e^(−tK²)
is CP and trace-nonincreasing.CPTP dephasing completion
DP(X) = PXP + QXQ
where Q = I − PTwo-sector fixed-space dimension
dim Fix(DP) = 47² + 78² = 8293Full-code QEC condition
PEₐ†EᵦP = αₐᵦP
remains the exact Knill–Laflamme requirement for a declared error model.
These corrections are explicitly recorded so that projection is not mislabeled as a full-space trace-preserving quantum channel.

X. Spatial-lift invariants
Internal protected rank under spatial extension
rank(Pinternal) = 47Spatial carrier may change while internal E47 rank remains fixed
Translation-invariant FCC × E47 construction
spatial Fourier structure and internal spectral selection remain typed as separate factors.
The registry classifies these finite periodic spatial constructions as exact/computationally verified within the declared models.
XI. ETNS / negative-space invariants
Observed/complement split
x = Px + (I − P)xNegative-space projector
H = I − PKernel/complement identities are exact
Epistemic boundary invariant
Mathematical absence does not, by itself, identify the hidden cause of that absence.
This separation between a mathematically defined complement and a causal interpretation is part of the City’s current evidence grammar.
XII. City-wide epistemic invariants
Claim-level evidence invariant
E0 = exact proof
E1 = executable reconstruction
E2 = simulation
E3 = external/empirical benchmark
E4 = experiment
H0 = hardwareEvidence non-transfer invariant
Evidence attached to one typed claim does not automatically promote another domain claim.Correction invariant
A corrected theorem preserves the provenance of the superseded statement rather than erasing it.Identity invariant
Re-rendering, re-exporting, or independently packaging an already identified mathematical object does not create a new mathematical citizen.Deduplication invariant
New proof artifacts can enlarge provenance while resolving to the same canonical identity.Boundary invariant
Exact finite mathematics, simulation, physical-model deduction, external measurement, and hardware realization remain distinct scopes.Typed-route invariant
A valid cross-domain bridge must explicitly specify its source object, target object, map, preserved structure, evidence class, and unresolved obligations.Canonical operational grammar
constraint → residual → projection → certificateExpanded civic grammar
typed input → reconstruction → verification → certificate → reconciliation → transitArchive invariant
Failed, corrected, duplicate, and superseded objects remain part of the audit trail without retaining canonical authority.
These are explicit architectural rules of the Mathematical City rather than extra mathematical assumptions.
