Product Inequalities and Log-Convexity Results for Struve Functions and Their First Derivative

Axioms
Some inequalities for products of Struve functions Hν(x) when |ν|≤12 are established using their infinite product formula as well as the arithmetic–geometric mean inequality. When these results are combined with some previously established results in the

On the Weighted AM--GM Inequality and Refined Inequalities Between Arithmetic Functions

Let \( \varphi(n) \), \( \psi(n) \) and \( \sigma(n) \) denote the Euler totient function and the Dedekind function respectively. Using improved versions of the weighted AM-GM inequality, we obtain a series of sharp upper bounds for \( \varphi(n)^{\varphi(n)} \psi(n)^{\psi(n)} \quad \text{and} \quad \varphi(n)^{\psi(n)} \psi(n)^{\varphi(n ...

Capital in Motion: Synthesizing the Circulation and Reproduction in a Multi‐Sector Growth Model

Metroeconomica, EarlyView.
ABSTRACT This paper analyzes Capital in Motion (CIM) in a capitalist economy, based on Karl Marx's Capital, Volume 2. It examines the circuit of capital, distinguishing between stock and flow variables, and integrates a multi‐sector growth model that combines the circuit and turnover of capital with the reproduction scheme.

(m1, m2) Geometric Arithmetically Convex Functions and Related Inequalities

, 2022
In this manuscript, we introduce and study the concept of $\\left( m_{1},m_{2}\\right) $-geometric arithmetically (GA) convex functions and their some algebric properties. In addition, we obtain Hermite-Hadamard type inequalities for the newly introduced this type of functions whose derivatives in absolute value are the class of $\\left( m_{1},m_{2 ...

Confidence Intervals for Price Discovery

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper discusses asymptotic and bootstrap confidence intervals for multivariate permanent‐transitory decompositions of cointegrated vector autoregressive I(1) systems, with a focus on price discovery. Alternative estimators of the permanent components are compared in terms of efficiency also under separable linear restrictions on the ...

Re‐Imagining Regulatory Governance

Regulation &Governance, EarlyView.
ABSTRACT This paper invites the readers to rethink regulatory governance by examining how trust‐based and rule‐based governance interact. To do this, it uses analytical narratives of three fictional polities: “Trustland”, “Regland”, and “Concordia”. Each polity represents a stylized model of governance: Trustland is anchored in trust‐based governance ...

Properties of a Linear Operator Involving Lambert Series and Rabotnov Function

International Journal of Mathematics and Mathematical Sciences
This work is an attempt to apply Lambert series in the theory of univalent functions. We first consider the Hadamard product of Rabotnov function and Lambert series with coefficients derived from the arithmetic function σn to introduce a normalized ...

Recognizing Our Role in Reframing Disaster and Emergency Management Terminology to Enhance Human Agency and Responsibility

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract This work addresses the critical issue of science literacy and science communication for scientists, researchers, officials, organizations, and the general public. Effective communication and trust between these groups are essential, particularly as the severity and scope of disasters continue to increase.

Quantitative asymptotics for polynomial patterns in the primes

Mathematika, Volume 72, Issue 3, July 2026.
Abstract We prove quantitative estimates for averages of the von Mangoldt and Möbius functions along polynomial progressions n+P1(m),…,n+Pk(m)$n+P_1(m),\ldots, n+P_k(m)$ for a large class of polynomials Pi$P_i$. The error terms obtained save an arbitrary power of logarithm, matching the classical Siegel–Walfisz error term.
