RST Equation Progression: Original → Generalized → Homogeneous
| Original Sourced Equation | Generalized Complete Equation | Homogeneous Special Case |
|---|---|---|
| (∂t² S − c² ∇² S + β S³) = σ(x,t) ⋅ FR(C[Ψ]) | d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = J(x,t) with J(x,t) = σ(x,t) ⋅ FR(C[Ψ]) |
d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = 0 |
| Field: S (substrate field). | Field: Φ (scalar field, replacing S). | Field: Φ (scalar field, self-contained). |
| ∂t² S: Inertial term (time evolution of substrate). | d²Φ/dt²: Inertial term (vacuum inertia, resistance to acceleration). | d²Φ/dt²: Same inertial term, no external source. |
| − c² ∇² S: Elastic term (wave propagation at finite speed). | − c² ∇² Φ: Elastic/dispersion term (finite-speed propagation). | − c² ∇² Φ: Same elastic term, applies internally. |
| + β S³: Nonlinear self-interaction (stabilizes knots/solitons). | + β Φ³: Nonlinear self-focusing (soliton formation, particle stability). | + β Φ³: Same nonlinear term, balances dispersion internally. |
| σ(x,t) ⋅ FR(C[Ψ]): Source term, coupling to external distributions and spinor configurations. | J(x,t): General source term, defined identically as σ(x,t) ⋅ FR(C[Ψ]). | No source term: RHS = 0, purely intrinsic dynamics. |
| No linear restoring term: Stability from nonlinear self-interaction and external source. | − μ Φ: New linear restoring term (background elasticity, equilibrium). | − μ Φ: Restoring term remains, ensures equilibrium without external input. |
| Equivalence: Matches generalized form if μ = 0 and S ↔ Φ. | General case: Includes both intrinsic terms and external source J(x,t). | Special case: J(x,t) = 0, reduces to self-contained homogeneous equation. |
✅ Takeaway
The progression shows how RST equations evolve: the Original form couples directly to external spinor sources, the Generalized form adds a linear restoring term and unifies intrinsic and external dynamics, and the Homogeneous case removes the source entirely, leaving a self-contained scalar field equation. Together, they illustrate how RST bridges external coupling and internal stability.
