Mathematical Content
Boundary Holonomy Correction
At galactic scales, the D-sector coupling receives a boundary holonomy correction that modifies the 1/r² force law:
g_eff(r) = g_N(r) · μ(g_N / a₀)
where:
-
g_N = GM/r² is the Newtonian acceleration
-
a₀ ~ cH₀ · f(ι_τ) is the MOND acceleration scale
-
μ(x) → 1 for x » 1 (Newtonian regime)
-
μ(x) → x for x « 1 (deep MOND regime → flat curves)
MOND Scale from ι_τ
The critical acceleration a₀ ≈ 1.2 × 10⁻¹⁰ m/s² is NOT a free parameter but derives from:
a₀ ~ c · H₀ · ι_τ^k
for an appropriate power k of ι_τ. This connects the galactic acceleration scale to the cosmic expansion rate and the master constant.
Radial Acceleration Relation (RAR)
The observed radial acceleration g_obs correlates tightly with the baryonic acceleration g_bar. This is the RAR:
g_obs = g_bar / (1 - exp(-√(g_bar/a₀)))
In the τ-framework, this emerges from a SINGLE D-sector coupling with boundary corrections — not from a tuned dark matter profile.

[V.T85] Flat rotation curve theorem: in the deep MOND regime (g « a₀), the circular velocity becomes independent of radius:
v_flat = (G · M · a₀)^{1/4}
This is the fourth root of the Tully-Fisher relation and explains why observed rotation curves flatten at large r without invoking dark matter.

[V.P68] Radial Acceleration Relation from single coupling: the tight correlation between observed and baryonic acceleration (McGaugh et al. 2016) emerges from a single D-sector coupling with boundary corrections.

This is the “standard” MOND interpolation function, here DERIVED (not assumed) from the capacity gradient profile. The capacity equation’s radial profile constrains:

The algebraic content of V.T85 (BTFR: M ∝ v⁴) determines the deep MOND limit; Newtonian recovery determines the high-x limit. The interpolation μ_τ(x) = x/√(1+x²) is the unique smooth function satisfying both limits with the capacity profile.

V.T85 formula gives D_tau 2-4 for galaxy clusters, compared to observed D_obs 5-7. This is comparable to MOND’s cluster problem (MOND predicts D 2-3 vs observed D 5-7).
Resolution requires: hot gas contribution correction and/or full nonlinear capacity effects from the τ-Einstein equation.

[V.P143] JWST Rotation Curve Predictions.
At z=2, a₀(z=2)/a₀(0) = H(z=2)/H(0) ≈ 3.03. For a fiducial galaxy (M_b = 10¹⁰ M☉): v_flat(z=0) ≈ 122.5 km/s v_flat(z=2) ≈ 161.5 km/s (31.9% higher)
Higher a₀ at z=2 means HIGHER v_flat for same mass, consistent with JWST observations of surprisingly flat rotation curves at z~1-3 (Genzel+2017, Nelson+2023).
BTFR normalization A(z) ∝ 1/H(z) decreases at high z. The τ-scale length ℓ_τ(z) = c/(H(z)·√κ_D) also shrinks.

[V.T205] c² Cancellation Theorem: in the linearized capacity equation, the c² factor cancels exactly between source and velocity extraction.
Source: (∇² − 1/ℓ²)u = −(4πG/c²)ρ → u ~ GM/(c²r) Extraction: v² = −(c²r/2)u′ → c² × c⁻² = 1 Net: v_cap² = GM·f(r/R_d, r/ℓ_τ)/r (independent of c)
The c² factor in V.T85 (v⁴ = GMc²/(2ℓ_τ)) is NOT accessible by any linearization of the capacity equation.
Verified numerically: point mass (3D), thin disk (2D, K₀), arbitrary density (Green’s function convolution), all to machine precision.
Physical content: the cancellation is a dimensional necessity. The capacity equation is a SCALAR equation with source 4πGρ/c². The c⁻² in the source is required by dimensional analysis (u is dimensionless). Extraction via v² = −(c²r/2)u′ re-introduces c² which exactly cancels the c⁻².

[V.T206] Metric-Capacity Coupling Source Theorem.
The linearized capacity equation sources scalar field u with: S_cap = 4πGρ/c² (scalar source, c⁻² suppressed)
The full τ-Einstein equation sources metric perturbation h₀₀ through the connection to the Newtonian potential Φ: h₀₀ = 2Φ/c² where ∇²Φ = 4πGρ (metric source)
In both cases, the perturbation scales as GM/(c²r). But the FLATTENING mechanism (K₀ profile → logarithmic potential) requires an amplitude set by the metric coupling a₀ = c²/(2ℓ_τ), which the scalar capacity equation cannot access.
The c² in V.T85 enters through a₀ = c²/(2ℓ_τ), a metric quantity that links the screening length ℓ_τ to the acceleration scale. It is NOT a PDE output but a structural consequence of the relativistic connection between c, ℓ_τ, and gravitational dynamics.

This factor is: • Far too large for perturbative corrections (weak-field ε ~ 10⁻¹³) • Not achievable by NF iteration convergence (refines, doesn’t amplify) • Bridged only by the algebraic identity a₀ = c²/(2ℓ_τ) (V.T207)

[V.P144] Nonlinear Amplification Pathway (conjectural).
IF the full nonlinear τ-Einstein equation is solved numerically at galactic scales, it should produce flat rotation curves with amplitude matching V.T85, because:
-
The metric perturbation h₀₀ receives a logarithmic profile from τ-screening (analogous to capacity K₀)
-
The amplitude of h₀₀ is set by the metric coupling
-
The geodesic equation yields v⁴ = GMc²/(2ℓ_τ)
This is conjectural pending numerical solution of the full nonlinear τ-Einstein equation at galactic scales. The V.T85 algebraic identity (V.T207) provides the answer without requiring this PDE solution.
