Eigenvalue Density, Li’s Positivity, and the Critical Strip [PDF]

open access: yes
We rewrite the zero-counting formula within the critical strip of the Riemann zeta function as a cumulative density distribution; this subsequently allows us to formally derive an integral expression for the Li coefficients associated with the Riemann xi-

Orthogonal polynomial expansions for the Riemann xi function

open access: yes, 2019
We study infinite series expansions for the Riemann xi function $ (t)$ in three specific families of orthogonal polynomials: (1) the Hermite polynomials; (2) the symmetric Meixner-Pollaczek polynomials $P_n^{(3/4)}(x; /2)$; and (3) the continuous Hahn polynomials $p_n\left(x; \frac34,\frac34,\frac34,\frac34\right)$.

On a positivity property of the Riemann ξ-function [PDF]

open access: yesActa Arithmetica, 1999
The functional equation for the Riemann zeta-function \(\zeta(s)\) is \(\xi(s) = \xi(1-s)\), where \[ \xi(s) := {\textstyle{1\over 2}}s(s-1)\pi^{-s/2}\Gamma( {\textstyle{1\over 2}}s)\zeta(s) = {\textstyle{1\over 2}}\prod_\rho {'} \left(1 - {s\over\rho}\right),\leqno(1) \] the product being taken over all complex zeros \(\rho\) of \(\zeta(s ...

Fourier Transforms of Positive Definite Kernels and the Riemann $$\xi $$ ξ -Function

open access: yesComputational Methods and Function Theory, 2015
The purpose of this paper is to investigate the distribution of zeros of entire functions which can be represented as the Fourier transforms of certain admissible kernels. The principal results bring to light the intimate connection between the Bochner-Khinchin-Mathias theory of positive definite kernels and the generalized real Laguerre inequalities ...

On a generalisation of the Riemann $\xi$-function

open access: yes, 2021
It is known that we can construct the meromorphic function $Z_k(s)$ associated with the higher derivative of Hardy's $Z$-function. In this paper, we introduce the entire function derived from $Z_k(s)$, a generalisation of the Riemann $\xi$-function and prove some properties.
