PVGS_DQ_Bridge.lean -- Photon-Varied Gaussian States → DualQuaternion Bridge
|
||
=============================================================================
|
||
|
||
Structural isomorphism between the PVGS framework (Giani, Win, Falb, Conti
|
||
2025–2026) and the DQ effective bound theory.
|
||
|
||
This file integrates five sections:
|
||
§1 PVGS Parameter Space in Dual Quaternion Components
|
||
§2 Generalized Hermite Polynomial → Sieve Bridge
|
||
§3 Complete Algebraic Variety Isomorphism
|
||
§4 RRC Hermite Kernel
|
||
§5 Quantum Sensing / Helstrom Bound Analysis
|
||
|
||
TYPE SYSTEM:
|
||
· Q16_16 — 16.16 fixed-point arithmetic (§1, §3 Dual Quaternions)
|
||
· ℚ — Rational numbers (§2 Hermite polynomials, §4 RRC kernel)
|
||
· ℝ — Real numbers (§5 Helstrom bound with Real.sqrt)
|
||
|
||
All type conversions are explicit (Q16_16.ofNat, ↑ casts, etc.).
|
||
No Q16_16 is mixed with ℚ or ℝ without explicit conversion.
|
||
|
||
FIXES APPLIED (from original file):
|
||
F1. hermite_sieve_isomorphism: replaced True := by trivial with a proper
|
||
theorem statement about the H-KdF sieve condition for repunit collisions.
|
||
F2. hermitianRRCKernel: replaced stub λ _ _ _ _ _ => 0 with the actual
|
||
H-KdF polynomial evaluation Hkdf m n (x:ℚ) ξ (x:ℚ) w (1/(x:ℚ)).
|
||
F3. variety_isomorphism: restructured as a conjunction with both the
|
||
forward (distinct energies) and backward (BMS bounds) directions.
|
||
F4. Type consistency: unified repunit definition (ℕ → ℕ), consistent
|
||
Q16_16 interface, explicit conversion points documented.
|
||
F5. Missing imports: all definitions defined inline or imported from
|
||
Mathlib. No dependency on Semantics.* modules.
|
||
|
||
STATUS: 8 of 10 sorrys FIXED. 2 remaining (documented):
|
||
• bms_implies_sieve — H-KdF computational verification (axiomatized)
|
||
• rrc_characterizes near-collision — needs BMS bounds as hypothesis
