An approximation of the Hurwitz zeta function by a finite sum

Lietuvos Matematikos Rinkinys, 2003
We obtain the following version of the approximation of the Hurwitz zeta-function. Let σ ≥ 0 and |t| ≤ π x. Then ζ(s, α) = ∑0 ≤ n ≤ x 1/(n + α)s +{ (x + α)1−s}/(s − 1) + Θ ({7√2π−1 + 3}/xσ).

Zeros of the Hurwitz zeta function in the interval (0,1) [PDF]

, 2011
We first give a condition on the parameters $s,w$ under which the Hurwitz zeta function $\zeta(s,w)$ has no zeros and is actually negative. As a corollary we derive that it is nonzero for $w\geq 1$ and $s\in(0,1)$ and, as a particular instance, the known

Some Relations of the Twisted q-Genocchi Numbers and Polynomials with Weight α and Weak Weight β

Abstract and Applied Analysis, 2012
Recently many mathematicians are working on Genocchi polynomials and Genocchi numbers. We define a new type of twisted q-Genocchi numbers and polynomials with weight 𝛼 and weak weight 𝛽 and give some interesting relations of the twisted q-Genocchi ...

Functional equations for zeta functions of groups and rings [PDF]

, 2010
We introduce a new method to compute explicit formulae for various zeta functions associated to groups and rings. The specific form of these formulae enables us to deduce local functional equations. More precisely, we prove local functional equations for

The Zeta and Related Functions: Recent Developments

Journal of Advanced Engineering and Computation, 2019
The main object of this survey-cum-expository article is to present an overview of some recent developments involving the Riemann Zeta function ζ(s), the Hurwitz (or generalized) Zeta function ζ(s, a), and the Hurwitz-Lerch Zeta function Φ(z, s, a ...

Generalized Cosecant Numbers and the Hurwitz Zeta Function

Integers, 2017
This announcement paper summarises recent development concerning the generalized cosecant numbers $c_{ρ,k}$, which represent the coefficients of the power series expansion for the important fundamental function $z^ρ/\sin^ρ z$. These coefficients are obtained for all, including complex, values of $ρ$ via the partition method for a power series expansion,

Mean Value Properties of the Hurwitz Zeta-Function.

MATHEMATICA SCANDINAVICA, 1992
Let \(\zeta^* (s,x) = \zeta (s,x + 1)\), where \(\zeta (s,a)\) \((0 < a \leq 1)\) is the Hurwitz zeta-function. The author proves that \[ \int^ 1_ 0 \left | \zeta^* \Bigl( {1 \over 2} + it, x \Bigr) \right |^ 2 dx = \log \left( {t \over 2 \pi} \right) + \gamma - 2 \text{Re} {\zeta (1/2 + it) \over 1/2 + it} + O \left( {1 \over t} \right), \] where ...

On the Hurwitz zeta function of imaginary second argument [PDF]

Journal of Mathematical Physics, 2011
In this work, we exploit Jonquière's formula relating the Hurwitz zeta function to a linear combination of polylogarithmic functions in order to evaluate the real and imaginary part of ζH(s, ia) and its first derivative with respect to the first argument s.

Moments of the Hurwitz zeta function on the critical line

, 2023
The Hurwitz zeta function is a shifted integer analogue of the Riemann zeta function, for shift parameters 0\u3c α ≤ 1. We consider the integral moments of the Hurwitz zeta function on the critical line ℛ(s)=½. We will focus on rational shift parameters.
