Generalized Complete Form of the RST Equation
RST Equation Comparison: Sourced vs. Homogeneous vs. Generalized
| Sourced Form | Homogeneous Form | Generalized Form |
|---|---|---|
| (∂t² S − c² ∇² S + β S³) = σ(x,t) ⋅ FR(C[Ψ]) | d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = 0 | d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = J(x,t), with J(x,t) = σ(x,t) ⋅ FR(C[Ψ]) |
| ∂t² S: Inertial term (time evolution of Substrate field). | d²Φ/dt²: Inertial term (vacuum inertia, resistance to acceleration). | d²Φ/dt²: Same inertial term, unified with source coupling. |
| − 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 in both sourced and homogeneous cases. |
| + β S³: Nonlinear self-interaction (stable knots/solitons). | + β Φ³: Nonlinear self-focusing (soliton formation, particle stability). | + β Φ³: Same nonlinear term, balanced against source J(x,t). |
| σ(x,t) ⋅ FR(C[Ψ]): Source term, coupling to matter/energy distributions and spinor configurations. | − μ Φ: Linear restoring term (background elasticity, equilibrium). No source term: Equation set equal to 0. |
J(x,t): General source term, defined as σ(x,t) ⋅ FR(C[Ψ]). Combines external coupling with intrinsic restoring force. |
| Field content: S couples to spinor functional C[Ψ], richer topological/spinor behavior. | Field content: Φ treated as scalar field, simplified dynamics without explicit spinor coupling. | Field content: Φ scalar field with optional spinor coupling via J(x,t). |
✅ Takeaway
The sourced form emphasizes external coupling, the homogeneous form highlights internal stability, and the generalized form unifies both: intrinsic Substrate mechanics on the left-hand side, external spinor/matter coupling on the right-hand side. This progression shows how RST equations evolve from externally driven to self-contained, while still allowing a general source term when needed.
Generalized Complete Form of the RST Equation
📐 The RST core equation can be written as:
d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = J(x,t)
with
J(x,t) = σ(x,t) ⋅ FR(C[Ψ])
🔹 What this means
Left-Hand Side (LHS):
- d²Φ/dt² → Inertial term (vacuum inertia, resistance to acceleration).
- − c² ∇² Φ → Elastic/dispersion term (finite-speed propagation).
- − μ Φ → Linear restoring term (background elasticity, equilibrium).
- + β Φ³ → Nonlinear self-focusing (soliton formation, particle stability).
Right-Hand Side (RHS):
- J(x,t) is the source term.
- Defined as σ(x,t) ⋅ FR(C[Ψ]), it represents coupling to external distributions and spinor configurations.
🔹 Special Cases
- Vacuum / no external coupling: If σ(x,t) ⋅ FR(C[Ψ]) = 0, then J(x,t) = 0. The equation reduces to the homogeneous form:
d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = 0 - Strict parity with the original sourced equation: If μ = 0 and S ↔ Φ, then the homogeneous form matches the original vacuum case.
✅ Takeaway
The generalized equation unifies both perspectives: the LHS describes intrinsic Substrate mechanics (inertia, elasticity, nonlinearity), while the RHS captures external coupling via σ(x,t) ⋅ FR(C[Ψ]). Setting J(x,t) = 0 recovers the homogeneous form, while keeping it explicit shows how RST links internal dynamics to external sources.
d²Φ/dt² − c² ∇² Φ − μ Φ + β Φ³ = J(x,t), with J(x,t) = σ(x,t) ⋅ FR(C[Ψ]).
