Green's functions and existence of solutions of nonlinear fractional implicit difference equations with Dirichlet boundary conditions [PDF]

Opuscula Mathematica
This article is devoted to deduce the expression of the Green's function related to a general constant coefficients fractional difference equation coupled to Dirichlet conditions. In this case, due to the points where some of the fractional operators are

A Mean Value Theorem for General Dirichlet Series

The Quarterly Journal of Mathematics
ABSTRACT In this paper we obtain a mean value theorem for a general Dirichlet series $f(s)= \sum_{j=1}^\infty a_j n_j^{-s}$ with positive coefficients for which the counting function $A(x) = \sum_{n_{j}\le x}a_{j}$ satisfies $A(x)=\rho x + O(x^\beta)$ for some ρ > 0 and β < 1. We prove that $\frac1T\int_0^T |\,f(\sigma+it)|^

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

From Inclusion to Sustainability: A Systematic Review of Research Trends in Sustainable Inclusive Education (2015–2025)

Sustainable Development, EarlyView.
ABSTRACT This systematic review reconceptualizes inclusive education (IE) as a cross‐cutting strategy for sustainable development. We analyze 2729 articles published between 2015 and 2025, identifying 357 that explicitly address sustainability. Using PRISMA 2020, bibliometric mapping, and binomial generalized linear models, we examine temporal ...

Generalized coefficients of the Dirichlet series

, 2021
The paper considers a method for converting a divergent Dirichlet series into a convergent Dirichlet series by directly converting the coefficients of the original series $1\rightarrow _{n}(s)$ for the Riemann Zeta function. In the first part of the paper, we study the properties of the coefficients $ ^*_n$ of a finite Dirichlet series for ...

Local labor market frictions and platform‐based entrepreneurship

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Building on prior research about the heterogeneous impact of labor shocks on individuals' propensity to start businesses, we explore how local labor market frictions affect individuals' selection into platform‐based entrepreneurship.

Is Reading an Upstream Predictor of Science and Mathematics Achievements in PISA? A Bayesian Network Analysis for Policy Educational Interventions on Socio‐Economic Dispersion and Gender Gaps

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This study investigates the structural relationships among reading, science and mathematics performance, socio‐economic dispersion (SES_Variance) and gender gaps using cross‐country PISA 2022 data. The primary objective is to assess whether reading functions as an upstream determinant of academic achievement and to evaluate the causal roles of

Generative AI in Financial Reporting

Journal of Accounting Research, EarlyView.
ABSTRACT Generative artificial intelligence (GAI) will likely alter many aspects of the financial reporting process and spawn a deep stream of academic research. We take an early step by examining the extent to which firms have begun using GAI in one important part of the reporting process: writing disclosures.

How Stock Market Participants Use Generative Artificial Intelligence: Evidence from User‐Platform Interaction Data

Journal of Accounting Research, EarlyView.
ABSTRACT This paper provides descriptive evidence on how stock market participants use Generative Artificial Intelligence (GenAI) to process investment‐related information. Using a data set of 1.7 million stock‐related queries from one of China's largest GenAI platforms during the first half of 2024, we document that user queries address a wide range ...
