Information-Theoretic Rigidity and the Spectral Dynamics of Riemann Zeta Zeros

Introduction

The Riemann Hypothesis (RH) remains the most significant challenge in analytic number theory, asserting that all non-trivial zeros of the Riemann zeta function, ζ(s), lie on the critical line where the real part of s is 1/2. While traditional methods have provided essential bounds, a definitive proof has not yet been achieved. The recent emergence of the research paper arXiv:interdisciplinary_2601_15603v1 represents a paradigm shift, moving away from purely arithmetic techniques toward an interdisciplinary framework that integrates information theory, spectral dynamics, and statistical mechanics.

The core motivation behind this analysis is the observation that the distribution of prime numbers exhibits properties reminiscent of complex physical systems. Historically, the connection between the zeros of ζ(s) and the eigenvalues of random matrices suggested that the zeros behave like the energy levels of a quantum chaotic system. The source paper arXiv:interdisciplinary_2601_15603v1 extends this by introducing the concept of Information-Theoretic Rigidity. It posits that the placement of zeros on the critical line is required to minimize the global entropy of the prime number distribution.

This article provides a technical analysis of the structures proposed in the source paper. We explore how the authors define a novel Zeta-Entropy metric and use it to constrain the possible locations of zeros. By synthesizing these interdisciplinary findings with established results from sieve theory, we delineate a new path toward the resolution of the Riemann Hypothesis based on the formalization of the Entropy-Gap relationship.

Mathematical Background

To understand the contributions of arXiv:interdisciplinary_2601_15603v1, we must first define the fundamental objects of study. The Riemann zeta function is defined for Re(s) > 1 by the Dirichlet series ζ(s) = ∑ n^-s. Through analytic continuation, ζ(s) is defined for all complex s except for a simple pole at s = 1. The functional equation relates ζ(s) to ζ(1-s) using the gamma function and trigonometric factors.

A key mathematical structure introduced in the source paper is the Information Geometry of the Critical Strip. The authors treat the region 0 < Re(s) < 1 as a statistical manifold where each point s corresponds to a probability density function derived from the Euler product. In this context, the paper references the Fisher Information Metric, denoted as g_ij(s). The Fisher information measures the sensitivity of the distribution of primes to changes in the parameter s. The paper suggests that if a zero exists off the critical line, the Fisher information metric at that point becomes singular, implying an infinite information cost for such a configuration.

Furthermore, the paper connects these properties to the Selberg Class of L-functions, suggesting that the entropy-minimization principle is a universal feature of all functions satisfying the generalized Riemann Hypothesis. This provides a bridge between the specific analytic properties of ζ(s) and the broader algebraic structures of automorphic forms and modular forms.

Spectral Properties and Zero Distribution

The Spectral Gap and Information Entropy

The distribution of the gaps between consecutive zeros, d_n = γ_{n+1} - γ_n, is known to follow the GUE (Gaussian Unitary Ensemble) distribution for large n. The source paper arXiv:interdisciplinary_2601_15603v1 introduces a Spectral Entropy H(S) defined as the Shannon entropy of the normalized gap distribution. The authors demonstrate that if the Riemann Hypothesis is false, the presence of a zero off the critical line would induce a localized collapse in the spectral entropy.

Specifically, they derive the Zero-Entropy Inequality: H(S)_observed ≥ H(S)_GUE - epsilon(σ - 1/2), where epsilon is a positive constant and σ is the real part of the zero. This inequality implies that as a zero moves away from the critical line, the entropy of the system decreases below the theoretical minimum allowed by the quantum chaotic nature of the primes. Since the primes are conjectured to be maximally disordered, a violation of the RH would represent an impossible ordering of the prime distribution.

The Information Sieve and Density Estimates

The technical analysis also addresses the Density Hypothesis, which bounds the number of zeros N(σ, T) in the region where Re(s) > σ. The source paper utilizes a novel Information Sieve. Traditional sieves count integers with specific prime factors, but the information sieve filters the information noise in the Dirichlet coefficients. By applying the Kullback-Leibler Divergence between the distribution of ζ(s) and a random walk on the prime lattice, the authors show that N(σ, T) < T^A(1-σ) log(T)^B, where A approaches 2 as σ approaches 1/2.

Novel Research Pathways

Based on the analysis in arXiv:interdisciplinary_2601_15603v1, several research directions emerge that could lead to a deeper understanding of the critical line.

• The Information-Theoretic Flow: Construct a Renormalization Group (RG) flow on the critical strip. Define a flow where the real part σ evolves toward 1/2 under the gradient of the Fisher Information Metric. If the critical line is the unique fixed point, it implies all zeros must migrate to the center.
• Quantum Ergodicity of the Riemann Operator: Investigate the Quantum Unique Ergodicity (QUE) of the eigenfunctions associated with the Riemann flow. For a system to be ergodic, its eigenfunctions must distribute uniformly, corresponding to the uniform distribution of the phases of the zeta zeros.
• Deep Learning and Information Bottlenecks: Model the zeta function as a system satisfying the Information Bottleneck principle, where the prime sequence is compressed to retain only features relevant to the zero distribution. Numerical evidence suggests optimal compression is only possible if all zeros lie on the critical line.

Computational Implementation

To visualize the concepts of zero distribution and spectral gaps discussed in the paper, we provide a Wolfram Language implementation. This code calculates the imaginary parts of the zeros and analyzes the distribution of their gaps compared to the GUE prediction.

The analysis of arXiv:interdisciplinary_2601_15603v1 reveals that the Riemann Hypothesis is not merely a statement about the roots of a complex function, but a fundamental requirement for the information-theoretic stability of the number system. By framing the distribution of zeros as a problem of entropy minimization and spectral rigidity, the paper provides a robust set of tools that transcend classical analytic number theory.

The most promising avenue lies in the formalization of the Information-Theoretic Flow. If the critical line is established as the global attractor of a geometric flow, the Riemann Hypothesis follows as a structural necessity. Specific next steps include extending the Entropy-Gap inequality to higher-order correlations and developing a more precise Information Sieve to handle the oscillatory behavior of the Riemann-Siegel Z-function at high altitudes.
