Notation Reference

ε — the break. The tension between the two conditions 0 and 1. Always Axiom B.

0, 1 — the two conditions of the substrate: 0 the fold (gravity, the black hole), 1 the propagation (light, matter, c).

a₀ — the transition (acceleration) scale. a₀ = cH₀/(2π) from the closure geometry; refined to αcH₀/(2π) in AP18.

H₀ — the Hubble parameter; the cosmological fold rate; the angular rate of one closure cycle (AP20).

T_ε — the tension field on the manifold, satisfying ∇·T_ε = 0 away from the poles (its field equation derived in Rosin V7, KS-42).

M•, rₛ — the central black-hole mass and its Schwarzschild radius rₛ = 2GM•/c².

rₜ — the transition radius, where the dense regime gives way to the floor.

σ — in the M•–σ relation, the galaxy velocity dispersion; elsewhere, where stated, the involution of Axiom S.

Λ — the cosmological constant (repulsive). Not the tension field.

Λ_sub — the dimensionless substrate stiffness scale, ≈ 2.15 × 10⁴⁶ (The Lock, Edition 04).

v — the rotation velocity; v⁴ ∝ M is the baryonic Tully-Fisher relation.
