The Riemann Hypothesis (RH) remains one of mathematics' most significant unsolved problems. This article proposes novel research pathways toward a proof, leveraging insights from the paper "hal-00576269." This paper presents a fascinating blend of spectral graph theory, group theory, and analytic number theory, particularly concerning the Euler-Mascheroni constant and prime products.
Several mathematical structures from the paper can be re-contextualized to address the RH.
Precise Mathematical Formulations: The paper references Mertens' formula for the Euler constant:
$$e^{\gamma}=\lim_{n \rightarrow \infty} \frac{1}{\log n} \prod_{p \leq n}\left(1-\frac{1}{p}\right)^{-1}$$
and analyzes related products and sums over primes:
$$-\sum_{p>x} \log \left(1-\frac{1}{(p-1)^{2}}\right)<-\int_{y}^{\infty} \log \left(1-\frac{1}{u^{2}}\right) du=-\left[u \log \left(1-\frac{1}{u^{2}}\right)+\log \left(\frac{u+1}{u-1}\right)\right]_{y}^{\infty} \sim \frac{1}{y} \sim \frac{1}{x}$$
Specific Theorems/Lemmas: We could construct theorems relating the convergence rate of these products to properties of the Riemann zeta function, particularly near the critical line.
Connection to Zeta Function: The Euler product formula for the Riemann zeta function provides a direct link:
$$\zeta(s) = \prod_{p \text{ prime}} \left(1-p^{-s}\right)^{-1}$$
Analyzing the convergence of the Mertens-like product in the paper, particularly its deviations from the Euler constant, might reveal information about the distribution of prime numbers and, consequently, the zeros of the zeta function.
Precise Mathematical Formulations: The paper analyzes the spectra of certain graphs (Ingested Paper Information, Point 4, 6):
Type 4: If $q=4r$, with $r$ an odd prime, $\operatorname{spec}\left(\mathcal{G}_{q}^{\star}\right)=\left\{q^{1}, 2^{2 r}, 0^{\psi(q) / 2},(-4)^{r},(-2 r)^{2}\right\}$.
Type 2: If $q=rs$, with $r, s$ two distinct primes, $\operatorname{spec}\left(\mathcal{G}_{q}^{\star}\right)=\left\{q^{1}, 1^{q},(-r)^{s},(-s)^{r}\right\}$.
Specific Theorems/Lemmas: We could explore whether these spectral properties have analogues in the operator theory related to the Riemann zeta function. A potential theorem could link the distribution of eigenvalues to the distribution of zeta zeros.
Connection to Zeta Function: The connection is less direct than with the prime products but could be established by constructing an operator whose spectrum reflects the zeros of the zeta function. The graph spectra could serve as a model for understanding the distribution of these eigenvalues.
Mathematical Foundation: Combine the Mertens-like asymptotics with the spectral analysis. Study how the convergence rate of the prime product influences the distribution of eigenvalues in a related operator.
Methodology: Construct an operator whose spectrum reflects the zeros of the Riemann zeta function. Then, investigate the relationship between the convergence rate of the prime products from the paper and the distribution of eigenvalues of this operator. This might reveal a connection between the prime number distribution and the location of zeta zeros.
Predictions: We might find that faster convergence of the prime product correlates with a more regular distribution of zeta zeros.
Limitations: Constructing the appropriate operator and proving the relationship between the prime product and the operator's spectrum will be challenging.
Formal Mathematical Bridges: The paper's focus on graph properties hints at potential connections with dynamical systems. Explore whether the evolution of a dynamical system can be modeled to reflect the distribution of primes and the zeros of the zeta function.
Specific Conjectures: We could conjecture that the long-term behavior of a carefully constructed dynamical system is related to the distribution of zeta zeros.
Computational Experiments: Simulate the dynamical system and analyze the long-term behavior. Compare the results with known data about the distribution of zeta zeros.
Conjectures:
Mathematical Tools: Analytic number theory, spectral graph theory, operator theory, dynamical systems theory.
Intermediate Results: Establishing bounds on the convergence rate of the modified Mertens product, constructing and analyzing the proposed operator, and observing consistent behavior in the dynamical system simulations would indicate progress.
Logical Sequence of Theorems: The research would proceed by first establishing results about the convergence rates and then connecting them to the operator's spectral properties. Finally, the dynamical system would be developed and analyzed.
Simplified Cases: Begin by applying the approach to simplified versions of the Riemann zeta function, for example, focusing on specific regions of the critical strip or considering simplified models of prime distribution.
