Canonical Stacks
A compact reference for the structural foundations stack and the Lorentzian Regime I stack. Click any item to expand its definition.
Structural Foundations Stack
M1 – M16M1Event SetStack▾
E is a nonempty set of events. Events are ontic; no background geometry is assumed.
M2Structural Time FieldStack▾
τ maps events to a totally ordered set. Only the order is physical; any strictly increasing relabeling is gauge.
M3Influence Partial OrderStack▾
≺ is a strict partial order compatible with τ: if e ≺ e′ then τ(e) < τ(e′).
M4Adjacency and NeighborhoodsStack▾
∼ is symmetric adjacency. Neighborhoods N(e) are finite, defining primitive locality without distances.
M5Collapse FieldStack▾
Φ assigns each event a real collapse value; variations across neighborhoods define collapse terrain.
M6Structural Time Validity IndicatorStack▾
X_struct(e)=1 when all neighbors lie strictly above or strictly below in τ; otherwise time is locally ambiguous.
M7Collapse Roughness FunctionalStack▾
R_Φ(e) sums squared collapse differences across N(e); large values indicate sharply structured collapse terrain.
M8Structural Time Shear FunctionalStack▾
S_τ(e) measures irregularity of τ-steps across N(e); small values indicate well-laminated stacks.
M9Structural ThresholdsStack▾
θ_c and θ_s set the minimum roughness and maximum shear required for robust classical structure.
M10Projection / Classicality DomainStack▾
D_QEC is the set of events with time valid, roughness high enough, and shear low enough.
M11Observer ChainsStack▾
Observers are influence-forward, time-increasing chains through the event network.
M12Structural Angle-of-Attack per StepStack▾
Δ_Γ(k)=τ(e_{k+1})−τ(e_k) defines stack ascent per link.
M13Structural AgingStack▾
Total aging is the sum of Δ_Γ(k) along a chain segment; an experienced version sums only within D_QEC.
M14Layered Collapse BrightnessStack▾
Brightness B_n is the total roughness in a τ-layer; it measures collapse activity per layer.
M15Arrow-of-Time PostulateStack▾
Brightness does not increase as τ advances: B_{n+1} ≤ B_n in the regime of interest.
M16Projection Weight SketchStack▾
A noncanonical sketch for weighting classical regions; included as a possible direction, not a foundation axiom.
Lorentzian Regime I Stack
L1 – L16L1Collapse FieldStack▾
Ψ_c is a real scalar field on an effective Lorentzian manifold; it encodes collapse terrain in the continuum regime.
L2Observer FieldStack▾
O^μ is a unit timelike vector field; its integral curves represent continuum observers.
L3Structural Time FieldStack▾
τ is a dynamical scalar field; it is interpretable as time only in collapse-active regions.
L4Time–Gradient InvariantStack▾
X is defined from the structural-time gradient and diagnoses whether τ behaves timelike.
L5Collapse-Active DomainStack▾
The collapse-active region is defined by X > 0.
L6τ-Sector LagrangianStack▾
A quartic-gradient effective Lagrangian yields stable second-order dynamics for τ.
L7Structural Time Field EquationStack▾
The canonical τ-PDE where X > 0.
L8Angle of AttackStack▾
dτ/ds = O^μ ∇_μ τ gives the rate of structural time along observer proper time.
L9Admissible ObserversStack▾
Admissible observers satisfy dτ/ds > 0, preventing closed-time behavior for physical chains.
L10Collapse PotentialStack▾
A representative double-well potential with a structural source term provides concrete collapse dynamics.
L11Collapse Equation of MotionStack▾
A covariant PDE governs Ψ_c evolution with coupling to the observer congruence.
L12Collapse IntensityStack▾
ρ is a positive-definite collapse intensity built from gradients of Ψ_c tangent to τ-slices.
L13Structural Shear of τStack▾
A shear norm measures local bending of τ-layers; bounded shear supports coherent projection.
L14Projection / Classicality DomainStack▾
D_QEC in the Lorentzian regime requires X>0, sufficient intensity, and bounded shear.
L15Observer Termination SurfaceStack▾
Projection-supporting observer evolution terminates when gradients vanish or shear exceeds threshold.
L16Collapse Brightness per LayerStack▾
Layer-wise brightness integrates ρ over the τ-slice within D_QEC; used for the arrow-of-time postulate.
