A new generalization of the Riemann zeta function and its difference equation

open access: yesAdvances in Difference Equations, 2011
We have introduced a new generalization of the Riemann zeta function. A special case of our generalization converges locally uniformly to the Riemann zeta function in the critical strip.

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.

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.

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.

The mean square of the product of the Riemann zeta-function with Dirichlet polynomials

open access: yes, 2017
Improving earlier work of Balasubramanian, Conrey and Heath-Brown [BCHB85], we obtain an asymptotic formula for the mean-square of the Riemann zetafunction times an arbitrary Dirichlet polynomial of length T , with δ = 0.01515 . . .. As an application we

Statistical disaggregation—A Monte Carlo approach for imputation under constraints

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Equality‐constrained models naturally arise in problems in which the measurements are taken at different levels of resolution. The challenge in this setting is that the models usually induce a joint distribution which is intractable. Resorting to instead sampling from the joint distribution by means of a Monte Carlo approach is also ...

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.
