dm³ Toy Model — Contact Manifold M = ℝ²₊ × ℝ

3000

Equations (4.1)–(4.3): ṙ = r(1−r²)+2(r−1)e⁻ᶻ, θ̇=1, ż = r²−2(r−1)²e⁻ᶻ. Limit cycle Γ₁₂ = {r=1} shown as dashed gold line. λ(z)=−2(1−e⁻ᶻ): neutral at z=0, attracting for z>0 (Prop. 4.2).

Theorem B — κ* ⟺ μ_max < 0 ⟺ τ ∈ (0,∞)

Theorem B (§3.3)

|κ| ↑ κ* ⟺ μ_max < 0 ⟺ τ = √(c/κ_noise) ∈ (0,∞).
κ* is the geometric precursor of τ: curvature accumulation creates the conditions under which stochastic stability becomes meaningful.

Proof: Forward → Thm 3.2 (Itô correction). Backward → Thm 3.4 (contradiction). Middle → Lemma 3.3.

Theorem 5.4 — Coherence Bridge: Six Domains, One Contact Normal Form

Coherence Bridge Theorem (§5.4)

The six dm³ systems are objects in the same category dm³ and are related by explicit contact morphisms f_ij : X_i → X_j satisfying f_ij(Γ_i) = Γ_j. The systems are not analogies — they are exact mathematical identities in the category dm³.

Corrected 2026-09-19 — the identity claim is withdrawn

“Identity” is a standard term with a decision procedure attached, and the procedure had never been run. Two matrices are similar exactly when they represent one linear map in different bases; near Γ each domain is a 2×2 system with eigenvalues μ ± iω. tools/coherence_similarity.py reads the eleven bridge rows that carry both numbers and tests every pair. Linear similarity: 0 of 55. Allowing the clock to be rescaled — comparing only the ratio μ/ω — 0 of 55. The closest pair is Immune adaptation (−2.4444) against Market volatility (−2.3929): near, not equal. What all eleven do share is that every 2D linear spiral sink is topologically conjugate to every other — true of eleven damped oscillators picked at random, so it carries no information about these eleven. The claim is true at the level where it says nothing and false at every level where it would say something. See ch20.

Contact normal form: ρ̇ = μ_max(1−e^{−βz})ρ + O(ρ²), θ̇ = ω + O(ρ), ż = ω−|μ_max|ρ²e^{−βz}+O(ρ³)

Lean 4 Proof Status — Honest Sorry Tracker

All sorry statements are open proof obligations. None are hidden. Green badges = closed in Lean 4. Red = open.

eigenvalue_at_zero PROVED

λ(0) = 0 — neutral stability at embodiment threshold.

simp [transverseEigenvalue] — closes immediately.

eigenvalue_neg_pos_z PROVED

λ(z) < 0 for z > 0 — attracting post-embodiment.

mul_neg_of_neg_of_pos + Real.exp_lt_exp against exp_zero. (exp_lt_one_of_neg, cited until V5, is not a Mathlib constant.)

toyModel_tau PROVED

τ = √(4/1) = 2 in closed form.

norm_num + Real.sqrt_eq_iff_sq_eq.

toyModel_epsilon0 PROVED

ε₀ = 2 / (2·(1+2)) = 1/3.

norm_num. Closes immediately.

thm_C_singularity_bijection PROVED

A2, A3 have unique preimages in the singularity correspondence.

cases + simp on finite inductive type.

eigenvalue_limit PROVED

λ(z) → μ_max as z → ∞.

Real.tendsto_exp_atBot composed with const_mul_atTop_of_neg. Closed 2026-08-26 (V5).

thm_A_contact_realization_fold PLACEHOLDER

H_diss → S(γ) as β→∞ in the distributional sense. The declaration's conclusion is True, not a sorry — so it passes every axiom check, which is why it is marked here rather than left to a badge.

★★★★☆ — distribution theory, not in Mathlib. The pointwise skeleton is proved: thm_A_regularization_pointwise (vanishes off the fold) and thm_A_regularization_at_fold (constant on it).

thm_B_threshold_equivalence TRIVIAL

The declaration proves μ_max < 0 ⟺ τ > 0, but from assumptions on both sides: each branch discards its hypothesis, and μ_max < 0 is a field of the DM3System structure. Each half is independently true and the arrow carries nothing.

★★★★★ — the full chain |κ|↑κ* ⟺ μ_max < 0 has no declaration at all. Needs Floquet + Has'minskii stochastic stability. Collaboration target.

OP1: Global Equivalence OPEN

Every τ-stable dm³ system arises from a fold globally on X.

Open problem (§6.3). Requires global contact topology.

OP2: Higher Resonances OPEN

k:m correspondence between higher Ak and higher resonances.

Open problem (§6.3). Requires Morse theory beyond A3.

Operator Sequence G = U ∘ F ∘ K ∘ C and Contact Extension

Volume I → Volume II Bridge

Volume I: C→K→F→U is a piecewise-smooth symplectic map on T*X. The fold F preserves ω = dγ∧dp (Theorem 11.1 [Vol I]).

Volume II: passes to contact extension M = X×ℝ, α = dz−λ, dλ = ω. The fold becomes H_diss = −γVe^{−βz} in the regularized limit β→∞.

Why Contact Geometry?

Liouville's theorem forbids attractors in symplectic systems on compact manifolds. Contact geometry provides: limit cycle attractors, stochastic stability, and variational structure simultaneously. The contact variable z records accumulated dissipation — the orbit earns its stability by accumulating action.
