A Covert Cyber‐Attack Framework and Detection on Communication Links in Linear Multi‐Agent Cyber‐Physical Systems

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
A covert attack architecture and detection approach in communication networks for homogenous and linear multi‐agent systems (MASs). A residual‐based detection method, exploiting a Kamlan filter observer and extra dynamic, is proposed to detect covert attacks on agents' communication channels.

Eco‐Epidemiological Mathematical Model Analysis With Time Delays and Hopf Bifurcation

open access: yesNatural Resource Modeling, Volume 39, Issue 2, May 2026.
ABSTRACT Ecological and infection predator prey mathematical model is important tool for understanding complex systems and forecasting outcomes biologically. Incorporating saturation mass action incidence rates representing the rate of susceptible prey infection as a function of time along with time delay terms, makes more realistic and reflective of ...

The holomorphic flow of the Riemann zeta function [PDF]

open access: yes, 2003
The flow of the Riemann zeta function, ś = ς(s), is considered, and phase portraits are presented. Attention is given to the characterization of the flow lines in the neighborhood of the first 500 zeros on the critical line.

Euler Numbers and Polynomials Associated with Zeta Functions

open access: yesAbstract and Applied Analysis, 2008
For s∈ℂ, the Euler zeta function and the Hurwitz-type Euler zeta function are defined by ζE(s)=2∑n=1∞((−1)n/ns), and ζE(s,x)=2∑n=0∞((−1)n/(n+x)s). Thus, we note that the Euler zeta functions are entire functions in whole complex s-plane, and these zeta ...

Wild conductor exponents of curves

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract We give an explicit formula for wild conductor exponents of plane curves over Qp$\mathbb {Q}_p$ in terms of standard invariants of explicit extensions of Qp$\mathbb {Q}_p$, generalising a formula for hyperelliptic curves. To do so, we prove a general result relating the wild conductor exponent of a simply branched cover of the projective line ...

SOME FORMULAS FOR APOSTOL-EULER POLYNOMIALS ASSOCIATED WITH HURWITZ ZETA FUNCTION AT RATIONAL ARGUMENTS [PDF]

open access: yes, 2020
We give some explicit relationships between the Apostol-Euler polynomials and generalized Hurwitz-Lerch Zeta function and obtain some series representations of the Apostol-Euler polynomials of higher order in terms of the generalized Hurwitz-Lerch Zeta ...

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.

On the modification of the universality of the Hurwitz zeta-function

open access: yesNonlinear Analysis, 2016
In the paper, the lower limit in the universality inequality for the Hurwitz zeta-function is replaced by an ordinary limit. The cases of continuous and discrete universalities are considered.

Hurwitz zeta functions and Ramanujan's identity for odd zeta values

open access: yesJournal of Mathematical Analysis and Applications, 2023
Inspired by a famous formula of Ramanujan for odd zeta values, we prove an analogous formula involving the Hurwitz zeta function. We introduce a new integral kernel related to the Hurwitz zeta function, generalizing the integral kernel associated to Ramanujan's identity.

An approximation of the Hurwitz zeta function by a finite sum

open access: yesLietuvos 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).
