Notation Reference

c — Speed of light. 299,792,458 m/s. Universal absorption limiter.

η — Leakage ratio. Fraction of incident energy that escapes an absorber.

ε — Symmetry-breaking parameter. Identified with η in section 7.

T_H — Hawking temperature. T_H = ℏc³/(8πk_BGM).

α — Fine-structure constant. e²/(4πε₀ℏc) ≈ 1/137.

γ — Domain coupling constant. G for gravity, α for electromagnetism.

G — Newton’s gravitational constant.

r_s — Schwarzschild radius. 2GM/c².

κ — Surface gravity (in section 1). Backreaction coupling (in section 8).

σ_abs — Absorption cross-section.

k_B — Boltzmann constant.

E_min — Landauer minimum erasure energy. k_B T ln 2.

Λ — UV scale (in section 8).

n_s — Spectral tilt. ≈ 0.965.

m_e — Electron mass. 0.511 MeV/c².

AS — Actualization state. The actualizing now — the surface from which records are written (AP01).
