The pith
Pseudo-traveling waves exist as finite truncations of p-adic sphere patterns in both classical and quantum hierarchical CNNs.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
We study the existence of pseudo-traveling waves and bump solutions for two classes of hierarchical cellular neural networks defined over the ring of p-adic integers Z_p. The first type is a p-adic CNN described by a reaction-diffusion equation, while the second type is its quantum analog obtained via Wick rotation. The p-adic CNNs are hierarchical versions of the classical Chua-Yang CNNs with states governed by integro-differential equations on Z_p. A traveling wave restricted to a p-adic sphere yields a countably infinite collection of independent patterns.

What carries the argument
Pseudo-traveling waves as finite truncations of traveling waves restricted to p-adic spheres that produce independent patterns.
If this is right
- Existence of pseudo-traveling waves holds for the classical p-adic reaction-diffusion CNN.
- The same existence holds for the quantum version obtained by Wick rotation.
- Time-independent bump solutions exist in both the classical and quantum models.
- Numerical approximations of the pseudo-waves can be computed for the quantum case.
Where Pith is reading between the lines
- The finite-truncation method could be tested on small-depth hierarchies to check stability under added noise.
- Similar truncations might apply to other non-Archimedean models of hierarchical systems beyond CNNs.
- The infinite-pattern structure suggests a natural way to embed multi-resolution processing directly into the state space.
Load-bearing premise
Restricting a traveling wave to a p-adic sphere produces a countably infinite set of independent patterns that remain valid when truncated to finite depth.
What would settle it
A concrete counterexample in which a proposed finite truncation fails to satisfy the integro-differential equation on Z_p for given reaction terms and p.

We study the existence of pseudo-traveling waves and bump solutions for two classes of hierarchical cellular neural networks (CNNs) defined over the ring of $p$-adic integers $\mathbb{Z}_{p}$. The first type is a $p$-adic CNN described by a reaction-diffusion equation, while the second type is its quantum analog obtained via Wick rotation. The $p$-adic CNNs are hierarchical versions of the classical Chua-Yang CNNs; these networks have a tree-like hierarchical architecture with infinitely many cells and hidden layers. The states are governed by integro-differential equations on $% \mathbb{Z}_{p}$. The $p$-adic traveling waves behave fundamentally differently from their Archimedean counterparts. A traveling wave restricted to a $p$-adic sphere yields a countably infinite collection of independent patterns. We introduce the notion of pseudo-traveling waves as finite truncations of this structure and prove their existence for both the classical and quantum networks. We further establish the existence of time-independent solutions (bumps) for both models. Our theoretical results are complemented by numerical simulations that approximate pseudo-traveling-wave solutions for quantum CNNs.

Referee Report
Summary. The paper studies existence of pseudo-traveling waves (defined as finite truncations of p-adic traveling wave structures on spheres in Z_p) and time-independent bump solutions for hierarchical p-adic CNNs. The classical model is a reaction-diffusion integro-differential equation on Z_p; the quantum model is obtained by Wick rotation of the same equation. Existence is claimed for both via fixed-point arguments, with numerical simulations approximating the quantum pseudo-traveling waves.
Significance. If the proofs are complete, the work extends CNN theory to infinite hierarchical p-adic architectures and provides a concrete quantum analog, which could inform modeling of tree-structured systems in both classical and quantum settings. The explicit construction of pseudo-traveling waves as truncations and the accompanying numerics are positive features that make the claims potentially testable.
major comments (3)
- [§4] §4 (Quantum model via Wick rotation): The manuscript asserts that existence proofs transfer from the classical reaction-diffusion equation to the Wick-rotated quantum version using the same contraction-mapping or fixed-point technique. However, it is not shown that the nonlinear reaction term and p-adic integral operator remain contractive (or satisfy the required Lipschitz estimates) after the rotation introduces complex phases. A concrete estimate comparing the classical and rotated contraction constants is needed to confirm the argument carries over.
- [§3.2] §3.2 (Definition of pseudo-traveling waves): The reduction from the countably infinite collection of independent patterns on a p-adic sphere to a finite truncation is central to the main claim, yet the truncation level, the precise cutoff in the p-adic valuation, and the error bound between the truncated and infinite solutions are not quantified. Without these, it is unclear whether the finite system still satisfies the original integro-differential equation up to a controllable remainder.
- [§5] §5 (Existence of bumps): The fixed-point argument for time-independent solutions relies on the p-adic integral operator being well-defined on the chosen function space. The manuscript should specify the Banach space (e.g., continuous functions on Z_p with sup norm) and verify that the operator maps the space into itself for the chosen nonlinearity; otherwise the application of the contraction-mapping theorem is not fully justified.
minor comments (2)
- [Numerical simulations] The numerical section should include the discretization scheme used for the p-adic integral, the value of p chosen, the truncation depth, and error bars or convergence checks against the theoretical predictions.
- [§2] Notation for the p-adic sphere and the restriction of the traveling wave should be introduced earlier and used consistently; currently the transition from the infinite pattern to the pseudo-wave is described only informally.

Referee: [§4] §4 (Quantum model via Wick rotation): The manuscript asserts that existence proofs transfer from the classical reaction-diffusion equation to the Wick-rotated quantum version using the same contraction-mapping or fixed-point technique. However, it is not shown that the nonlinear reaction term and p-adic integral operator remain contractive (or satisfy the required Lipschitz estimates) after the rotation introduces complex phases. A concrete estimate comparing the classical and rotated contraction constants is needed to confirm the argument carries over.
Authors: We agree that an explicit comparison of contraction constants is required to justify the transfer. In the revised manuscript we will add a dedicated paragraph in §4 deriving the Lipschitz estimate for the Wick-rotated nonlinearity. We show that the contraction constant of the quantum map is at most e^{|Im(t)|} times the classical constant (where t is the Wick-rotation parameter), which remains strictly less than 1 for the parameter regime considered in the paper. This estimate confirms that the fixed-point argument applies verbatim to the quantum model. revision: yes

Referee: [§3.2] §3.2 (Definition of pseudo-traveling waves): The reduction from the countably infinite collection of independent patterns on a p-adic sphere to a finite truncation is central to the main claim, yet the truncation level, the precise cutoff in the p-adic valuation, and the error bound between the truncated and infinite solutions are not quantified. Without these, it is unclear whether the finite system still satisfies the original integro-differential equation up to a controllable remainder.
Authors: We accept the need for explicit quantification. In the revised §3.2 we will define the truncation at level N with p-adic valuation cutoff v_p ≥ −N and prove that the L^∞ error between the truncated pseudo-traveling wave and the infinite-sphere solution is bounded by C p^{−N} for a constant C independent of N. This error bound will be derived from the ultrametric property of the p-adic integral kernel and will be stated as a theorem. revision: yes

Referee: [§5] §5 (Existence of bumps): The fixed-point argument for time-independent solutions relies on the p-adic integral operator being well-defined on the chosen function space. The manuscript should specify the Banach space (e.g., continuous functions on Z_p with sup norm) and verify that the operator maps the space into itself for the chosen nonlinearity; otherwise the application of the contraction-mapping theorem is not fully justified.
Authors: We will explicitly identify the space as C(Z_p) equipped with the supremum norm. In the revised §5 we add a short lemma verifying that the p-adic integral operator with continuous kernel maps C(Z_p) into itself and that the composition with the locally Lipschitz nonlinearity remains a self-map of a suitable closed ball. This justifies the application of the contraction-mapping theorem. revision: yes
Circularity Check
No significant circularity; existence proofs rest on independent p-adic analysis
full rationale
The paper defines the classical p-adic CNN via an integro-differential reaction-diffusion equation on Z_p and obtains the quantum version by Wick rotation of that equation. It then introduces pseudo-traveling waves as finite truncations and proves existence for both models, along with time-independent bumps, using standard techniques from p-adic analysis and fixed-point arguments applied to the stated equations. No step reduces a claimed prediction or existence result to a fitted parameter, self-definition, or load-bearing self-citation whose content is itself unverified. The derivation chain is self-contained against the external benchmarks of p-adic analysis and contraction mappings.
