Computational No-Coincidence
Neyman's CNCC in Lean 4
Extended Research — Eric Neyman (ARC, 2025) | Formalized March 15, 2026
Overview
Eric Neyman (ARC, 2025) conjectures that for reversible circuits on exhibiting a “non-coincidental” zero-suffix property, there exist short advice strings that serve as polynomial-time verifiable structural explanations. This formalization does not prove CNCC itself — it builds a candidate verifier architecture that makes the conjecture's structure explicit.
The key insight: advice strings are naturally modeled as nucleus operators (closed, idempotent, order-preserving maps) on the lattice of circuit properties. This turns the informal notion of “structural explanation” into a formally tractable fixed-point condition. The core theorem () proves a genuine biconditional: gap = 0 iff all accepted circuits have the target property.
