On two conjectural series involving Riemann zeta function [PDF]

open access: yesarXiv, 2023
Riemann zeta function is important in a lot of branches of number theory. With the help of the operator method and several transformation formulas for hypergeometric series, we prove four series involving Riemann zeta function. Two of them are series expansions for $\zeta(7)$ and $\zeta(3)^2$ recently conjectured by Z.-W. Sun.

Optimizing calibration designs with uncertainty in abilities

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Before items can be implemented in a test, the item characteristics need to be calibrated through pretesting. To achieve high‐quality tests, it's crucial to maximize the precision of estimates obtained during item calibration. Higher precision can be attained if calibration items are allocated to examinees based on their individual abilities ...

A Derivation of π(n) Based on a Stability Analysis of the Riemann-Zeta Function [PDF]

open access: yes, 2010
The prime-number counting function π(n), which is significant in the prime number theorem, is derived by analyzing the region of convergence of the real-part of the Riemann- Zeta function using the unilateral z-transform.

Universality of the Riemann zeta-function

open access: yesJournal of Number Theory, 2010
AbstractIn 1975, S.M. Voronin proved the universality of the Riemann zeta-function ζ(s). This means that every non-vanishing analytic function can be approximated uniformly on compact subsets of the critical strip by shifts ζ(s+iτ). In the paper, we consider the functions F(ζ(s)) which are universal in the Voronin sense.

Fractional gaussian noise: Spectral density and estimation methods

open access: yesJournal of Time Series Analysis, EarlyView.
The fractional Brownian motion (fBm) process, governed by a fractional parameter H∈(0,1), is a continuous‐time Gaussian process with its increment being the fractional Gaussian noise (fGn). This article first provides a computationally feasible expression for the spectral density of fGn.

Cointegrating Polynomial Regressions With Power Law Trends

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

Metamaterials and Cesàro convergence

open access: yesAIP Advances, 2020
In this paper, we show that the linear dielectrics and magnetic materials in matter obey a special kind of mathematical property known as Cesàro convergence.

The limit of the Riemann zeta function and its nontrivial zeros [PDF]

open access: yesarXiv, 2019
In this article, with a new approach, which is not discussed in the literature yet, the limit of the Riemann zeta function or Euler-Riemann zeta function is approximately explored by applying Dirichlet's rearrangement theorem for absolutely convergent series to the Riemann zeta function by rearranging its terms as geometric series for sufficiently ...

Almost all of the nontrivial zeros of the Riemann zeta-function are on the critical line [PDF]

open access: yesarXiv, 2022
Applying Littlewood's lemma in connection to Riemann's Hypothesis and exploiting the symmetry of Riemann's $xi$ function we show that almost all nontrivial Riemann's Zeta zeros are on the critical line.
