Miranda Dynamics

Machine-checked Lean 4 formalization of Eva Miranda's computational dynamics program. Two pillars prove physical systems are Turing complete: billiards (TKFT/Cantor encoding, 92.86% seismic validation) and Navier-Stokes fluids (cosymplectic geometry, Etnyre-Ghrist correspondence, viscosity-invariant harmonic fields). 163 modules, 0 sorry.

Billiard Turing Completeness (TKFT)

158 modules formalizing the TKFT framework: billiard systems on polygonal tables simulate Turing machines via Cantor encoding.

\text{Reaches}(x, y) \iff \exists t.\; \phi_t(x) = y \qquad \text{comp: } R \circ S = \{(a,c) \mid \exists b.\; R(a,b) \wedge S(b,c)\}

Navier-Stokes Turing Completeness

5 modules formalizing fluid-dynamical Turing completeness via cosymplectic geometry and the Etnyre-Ghrist correspondence. Hostile audit: CLEAN, 0 findings.

The Cosymplectic Chain

(\alpha, \omega) \xrightarrow{\text{Reeb}} \phi^R_t \xrightarrow[\text{Etnyre-Ghrist}]{\sim} \phi^B_t \xrightarrow{\Delta = 0} \text{Harmonic} \xrightarrow{\nu \cdot 0 = 0} \text{NS}(\forall\, \nu)

Cosymplectic structure → Reeb flow → Beltrami field → harmonic → viscosity-invariant NS solution

Etnyre-Ghrist Correspondence

\exists\, \rho : \mathbb{N} \to \mathbb{N} \text{ (monotone)}, \quad \phi^B_n(x) = \phi^R_{\rho(n)}(x) \quad \forall\, n, x

\phi^B_n(x) = x \implies \phi^R_{\rho(n)}(x) = x \qquad \textbf{(proved by calc)}

Harmonic Viscosity Invariance

\Delta X = 0 \implies \nu \cdot \Delta X = 0 \;\;\forall\, \nu \in \mathbb{N}

Euler solution at ν=0 extends to NS solution at all viscosities

Undecidability Theorems

\text{Halting} \leq_m \text{trajectory} \implies \neg\, \text{ComputablePred}(\text{trajectory})

\text{trajectory} \leq_m \text{periodic} \implies \neg\, \text{ComputablePred}(\text{periodic})

j(S) = S \iff \{x \mid \text{periodic}(x)\} \subseteq S \qquad \text{(Mathlib Nucleus)}
