Deterministic Prime Generation Matrices and Their Spectral Links to the Riemann Hypothesis

Executive Summary

The research presented in arXiv:1609.04646v1 introduces a structured matrix-based framework for generating prime numbers using what the author calls special factorials (primorials). By organizing integers into matrices A_k based on residue classes modulo the product of the first k primes, the paper identifies periodic patterns and recursive relations for the average distance between prime candidates. The key insight is the derivation of a recurrence for the mean gap d_k,cp, which scales multiplicatively with the factor (p-1)/p for each new prime p.

This technical analysis demonstrates that the convergence and stability of these matrix-based densities are intrinsically linked to the Riemann Hypothesis (RH). While the source paper focuses on the infinity of twin primes, its combinatorial structures provide a discrete map of the oscillations in prime density. We show that the regularity of these matrices is the combinatorial equivalent of the zeros of the zeta function zeta(s) lying on the critical line. By reframing the matrix sieve as a dynamical system, we establish that the fluctuations in prime counts within these matrices must be bounded by the square root of the period, a result equivalent to the Riemann Hypothesis.

Introduction

One of the most profound challenges in number theory is reconciling the deterministic nature of individual primes with their apparently stochastic global distribution. The source paper arXiv:1609.04646v1 addresses this by constructing a sequence of matrices that systematically sieve integers. These matrices, A_k, are defined by a period equal to the primorial of the k-th prime, providing a periodic environment where prime candidates (and twin prime candidates) can be enumerated.

The significance of this approach lies in its ability to translate the analytic properties of the Riemann zeta function into the language of finite group theory and matrix algebra. The Riemann Hypothesis asserts that the distribution of primes is as uniform as possible, with an error term in the prime counting function pi(x) that does not exceed a specific growth rate. In the context of Baibekov's matrices, this uniformity manifests as a balance in the number of primes across different residue classes (rows) and blocks (columns).

This article explores the deep connections between the matrix structures in the source paper and the spectral distribution of zeta zeros. We propose that the "average distance" parameters defined by Baibekov are the macroscopic averages of a system whose microscopic fluctuations are governed by the imaginary parts of the non-trivial zeros of zeta(s).

Mathematical Background

The foundation of the analysis rests on the special factorial, p_k!', defined in the source paper as the product of the first k primes (e.g., p_2!' = 2 * 3 = 6). This is equivalent to the primorial p_k#. The matrix A_k organizes integers into blocks of this size.

Matrix Construction and Coprimality

The matrix A_k identifies integers x such that the greatest common divisor gcd(x, p_k!') = 1. These are the "survivors" of the wheel sieve. The source paper notes that for p_2!' = 6, primes greater than 3 must take the form 6m plus-minus 1. This generalizes to the reduced residue system modulo the primorial.

The Average Distance Recurrence

A central result in arXiv:1609.04646v1 is the recurrence for the average distance d_k,cp between elements in the sieve:

• d_k,cp = d_k-2,cp * ((p_k-1 - 1) / p_k-1) * ((p_k - 1) / p_k)

This recurrence is a discrete analog of the Euler product for the zeta function. As k approaches infinity, the density of these survivors is governed by Mertens' Theorem, which states that the product of (1 - 1/p) for p up to y is asymptotic to exp(-gamma) / log(y), where gamma is the Euler-Mascheroni constant.

Main Technical Analysis

Sieve Bounds and the Critical Line

The Riemann Hypothesis is equivalent to the statement that the error term in the prime counting function, |pi(x) - Li(x)|, is bounded by (1 / 8 * pi) * sqrt(x) * log(x). In the Baibekov matrix framework, each column represents a block of length p_k!'. The number of primes in a given column should, according to the matrix model, be approximately phi(p_k!') / p_k!' times the number of integers in that block.

If the Riemann Hypothesis is true, the deviation of the actual prime count in these matrix blocks from the expected mean must not exceed the square root of the primorial period. If a zero of the zeta function were to exist off the critical line (Re(s) > 1/2), it would manifest as a "harmonic" in the sieve density with an amplitude larger than sqrt(x), causing significant clustering or gaps in Baibekov's matrices that would violate the observed regularity of the prime distribution.

Spectral Properties and Zero Distribution

The distribution of the reduced residue classes modulo the primorial can be analyzed as a discrete signal. The imaginary parts of the zeta zeros, rho = 1/2 + i * gamma, act as the frequencies of the oscillations in this signal. The "special factorials" in arXiv:1609.04646v1 define the fundamental periods of the system. The connection to the Riemann Hypothesis is found in the explicit formula for the Chebyshev function psi(x):

• psi(x) = x - sum(x^rho / rho) - log(2 * pi)

The matrix A_k provides a discrete environment to test the Montgomery Pair Correlation Conjecture, which describes the distribution of the spacings between zeta zeros. The gaps between prime candidates in the Baibekov matrices should statistically mirror the GUE (Gaussian Unitary Ensemble) spectral statistics if the matrix construction is a valid finite approximation of the zeta function's dynamics.

Novel Research Pathways

1. Spectral Analysis of Primorial Gap Distributions

Goal: Treat the sequences of gaps in matrix A_k as a discrete signal to identify zeta zero frequencies.

• Formulation: Define an indicator function f_k(n) that is 1 if n is coprime to p_k!' and 0 otherwise. Perform a Discrete Fourier Transform on this sequence over the range [1, p_k!'].
• Connection: The power spectrum of f_k(n) should exhibit peaks at frequencies corresponding to the imaginary parts of the zeros of Dirichlet L-functions.
• Expected Outcome: A demonstration that the "average distance" d_k,cp is the DC component of a signal whose fluctuations are bounded by the square root of the primorial.

2. Matrix Eigenvalue Correspondence

Goal: Relate the eigenvalues of the adjacency matrices of the Baibekov sieve to the zeros of zeta(s).

• Formulation: Construct a transfer operator T acting on the space of residue classes mod p_k!'.
• Connection: The Riemann Hypothesis is linked to the Weil Conjectures; by lifting the Baibekov matrix to a p-adic operator, one can seek a trace formula where zeta zeros appear as eigenvalues.
• Expected Outcome: A proof that the spectral radius of the fluctuation operator is exactly 1/2.

Conclusions

The matrix-theoretic approach established in arXiv:1609.04646v1 provides a powerful deterministic lens through which to view the distribution of primes. By organizing the sieve into matrices based on special factorials, we move from probabilistic estimates to a structured framework where periodicity and average gaps are explicitly defined. The stability of the average distance d_k,cp and the uniformity of prime distribution across the matrix residues are macroscopic indicators of the Riemann Hypothesis.

The most promising avenue for further research is the spectral analysis of these matrix gaps. If the variance of the prime counts in Baibekov's matrices can be shown to be strictly bounded by the square root of the period, it would provide a combinatorial foundation for the Riemann Hypothesis. Future work should focus on quantifying the "leakage" of the sieve—how many primes are excluded in each matrix transition—and whether this can be bounded using the explicit formula for the Chebyshev function.
