Click For Summary

Discussion Overview

The discussion revolves around a proposed Hamiltonian operator related to the Riemann Hypothesis, specifically focusing on the connection between the operator's eigenvalues and the imaginary parts of the zeros of the Riemann Zeta function. The conversation includes theoretical considerations, mathematical formulations, and the implications of using physics terminology in a mathematical context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant proposes a Hamiltonian operator whose eigenvalues correspond to the imaginary parts of the Riemann Zeta function's zeros, using semiclassical WKB evaluation methods.
  • Another participant questions the use of physics terminology, suggesting that a mathematical formulation would be more appropriate for discussing the Riemann Hypothesis.
  • There are discussions about the asymptotic nature of certain approximations, with some participants emphasizing the need for error terms in mathematical expressions.
  • Some participants express skepticism about the validity of the proposed definitions and the existence of the potential function V(x), asking for clarity and exact definitions.
  • One participant claims to have verified the first three eigenvalues of their Hamiltonian using semiclassical methods, although these values do not match the known imaginary parts of the Riemann Zeta function's zeros.
  • Concerns are raised regarding the accuracy of approximations and the transition from asymptotic results to exact values.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of using physics terminology in a mathematical context, the validity of the proposed Hamiltonian, and the accuracy of the results obtained. There is no consensus on the correctness of the claims made regarding the Hamiltonian operator and its implications for the Riemann Hypothesis.

Contextual Notes

Participants note that the proposed definitions and results are based on approximations, and there are discussions about the limitations of these approximations in achieving exact values. The conversation also highlights the dependence on specific mathematical formulations and the challenges in transitioning from theoretical models to concrete results.

a bit of explanation ..

QUANTUM MECHANICS AND SEMICLASSICAL SOLUTIONS

the schröedinguer equation in units \hbar = 2m=1 for one dimensional particle under the influence of a potential f(x) is

-D^{2} y(x)+f(x)y(x)=E_{n}y(x)

here the eigenfunctions are on an L^{2} (R) space so \int_{-\infty}^{\infty}dx|y(x)|^{2} < \infty

of course this equation is complicate to solve EXACTLY depending on the form of f(x) so we still must rely on approximations

y(x) \approx e^{iS(X)} , here S(x) is a function that satisfy the first order differential equation (1)

E= (\frac {dS}{dx})^{2}+f(x) and here 'E' is the Energy

from the ansatz in (1) we obtain the following APPROXIMATE (is an approximate solution INVALID in mathematics ? ) for the quantization of Energies

\pi n(E) = \int_{0}^{a}dx (E-V(x))^{1/2} (2)

here 'a' is TURNING POINT , in other words 'a' is a value of position 'x' so E=V(x) as you will notice if the POtential is bigger than the Energy the integrand is COMPLEX

This integral equation in (2) has NO exact solution for V(x) but can be solved to get the INVERSE of the potential function f(x) so f^{-1} (x) = 2 \sqrt \pi \frac{d^{1/2}n(x)}{dx^{1/2}}

ONCE we have the INVERSE we could solve this equation by numerical methods to get f(x) and then solve NUMERICALLY the Schroedinguer equation -D^{2} y(x)+f(x)y(x)=E_{n}y(x)

this is WHY quantum mechanic is RELEVANT to solve the RIemann Hypothesis, AGAIN my question for the mathematician is

AN APPROXIMATE EQUATION IS STILL VALID ? , of course perhaps the EIGENVALUES will be ASYMPTOTICS to the zeros , is this still invalid ??

also you can check this formula for the HARMONIC OSCILLATOR or LINEAR POTENTIAL to check that gives CORRECT results

Also, if we consider the Riesz function , R(x) that under Riemann HYpothesis satisfies

R(x)=O(x^{1/2+\epsilon} ) for any positive epsilon

this Riesz function satisfy the integral equation

e^{-x}-1 = \int_{0}^{\infty} \frac{dt}{t}R(t)frac( ( xt^ {-1})^{1/2})

so if we consider R(x)=O(x^{1/2+\epsilon} ) and plug it into the integral you get that e^{-x}-1 \le C \frac{ |\zeta (1/2+2\epsilon)|}{1+2\epsilon}x^{1/4+ \epsilon}

the inverse of the potential is given by

AV^{-1}(x)= \sum_{\gamma}H(x-\gamma^{2})(x-\gamma^{2})^{-1/2}

using the Riemann-Weyl formula this sum can be turned into a sum over primes and prime powers.
