Toward P vs NP: An Observer-Theoretic Separation via SPDP Rank and a ZFC-Equivalent Foundation within the N-Frame Model

TL;DR

The paper develops an observer-centered, ZFC-friendly framework to separate P from NP by encoding polynomial-time computations into SPDP (Shifted Partial Derivative) polynomials and measuring their complexity with Contextual Entanglement Width (CEW). A deterministic, radius-1 compiler maps DTMs to local SoS polynomials with polylog CEW, enabling a Width→Rank bound that yields polynomial SPDP rank for P-time computations, while explicit NP witnesses (e.g., Ramanujan–Tseitin expanders) force exponential SPDP rank. An instance-uniform extraction map (the Global God-Move) relates P-compiled polynomials to NP instances under a fixed gauge, producing a contradiction if P=NP. The work unifies algebraic (SPDP) and epistemic (CEW) perspectives through the N-Frame observer model, and argues non-relativizing, non-natural-proof barriers are circumvented by the structure of the construction. The result is an unconditional, machine-checkable blueprint (with Lean formalization planned) for a complete P≠NP separation within a coherent, observer-centric framework that connects computational, algebraic, and epistemic notions of hardness.

Abstract

We present a self-contained separation framework for P vs NP developed entirely within ZFC. The approach consists of: (i) a deterministic, radius-1 compilation from uniform polynomial-time Turing computation to local sum-of-squares (SoS) polynomials with polylogarithmic contextual entanglement width (CEW); (ii) a formal Width-to-Rank upper bound for the resulting SPDP matrices at matching parameters; (iii) an NP-side identity-minor lower bound in the same encoding; and (iv) a rank-monotone, instance-uniform extraction map from the compiled P-side polynomials to the NP family. Together these yield a contradiction under the assumption P = NP, establishing a separation. We develop a correspondence between CEW, viewed as a quantitative measure of computational contextuality, and SPDP rank, yielding a unified criterion for complexity separation. We prove that bounded-CEW observers correspond to polynomial-rank computations (the class P), while unbounded CEW characterizes the class NP. This implies that exponential SPDP rank for #3SAT and related hard families forces P != NP within the standard framework of complexity theory. Key technical components include: (1) constructive lower bounds on SPDP rank via Ramanujan-Tseitin expander families; (2) a non-circular reduction from Turing-machine computation to low-rank polynomial evaluation; (3) a codimension-collapse lemma ensuring that rank amplification cannot occur within polynomial resources; and (4) proofs of barrier immunity against relativization, natural proofs, and algebrization. The result is a complete ZFC proof architecture whose primitives and compositions are fully derived, with community verification and machine-checked formalization left as future work.

• Figure 1: Computational holography: SPDP collapse and the bulk function $f_n$. Schematic 3-D view of the SPDP collapse boundary (translucent dome) under radius = 1, diagonal basis, and $\Pi^+ = A$. Blue crosses depict representative P-computable workloads that remain inside the dome, where codimension-pruned rank is polynomial. The red star indicates the target hard family $f_n$ outside the boundary, where rank necessarily inflates. This figure is conceptual; quantitative evidence appears later via the compiler, CEW bounds, and width$\Rightarrow$rank lemmas.
• Figure 2: Semantic inference geometry in the N-Frame observer frame model, illustrating how computational complexity emerges from observer-bounded inference and the curvature of the epistemic landscape. The observer frame $F = (S, R, I)$ acts as a lens whose curvature is quantified by SPDP rank, which serves as the basis for CEW (Contextual Entanglement Width).
• Figure 3: Roadmap of the $P \neq NP$ proof structure, illustrating the progression from classical foundations through the SPDP rank framework (with PAC-style compilation bounds) and the observer-theoretic layer (structural CEW as interface capacity) to the final separation result. SPDP rank $\Gamma^{B}_{\kappa,\ell}$ is the load-bearing algebraic invariant; structural CEW provides the upstream architectural bridge via Width$\Rightarrow$Rank. The layered design highlights the correspondence between mathematical, epistemic, and potential future formal components of the proof architecture.

• Figure 5: Rank gap at matching parameters (NP lower bound).$Q^{\times}_{\Phi_n}$ exhibits an identity-minor of size $n^{\Theta(\log n)}$ at $(\kappa,\ell)=\Theta(\log n)$; this contradicts the P-side upper bound under the rank-monotone extraction $\mathcal{T}_\Phi$ (Lemma \ref{['lem:god-move-properties']}). All quantities are measured under the fixed compiled/blocked SPDP rank $\Gamma^{B}_{\kappa,\ell}$ at parameters $(\kappa,\ell)=\Theta(\log n)$; the separation is instance-uniform but parameter-fixed.
