The Modified q-Euler numbers and polynomials

open access: yes, 2007
In the recent paper the interesting q-Euler numbers and polynomials introduced in JMAA. The purpose of this paper is to construct the modified q-Euler numbers and polynomiasl. Finally we will give the interesting many identities related to these numbers and polynomials.

On a family of Euler-type numbers and polynomials

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2023
Summary: We consider a family of Euler-type polynomials, depending on a real parameter \(\alpha \neq 0, 1\). The case \(\alpha = 2\) corresponds to standard Euler polynomials. We show some properties of these polynomials, and show also two generalized recurrences.

Pre‐ Versus Post‐Breeding Population Projection Models? A Simple Fix to a Common Parametrization Error

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Population Projection Models (PPMs) are essential tools in demographic studies for predicting the growth of structured populations. This work introduces a simple, robust method for constructing pre‐ and post‐breeding projection matrices called MAP for Matrices Alternated Products directly from empirical data, addressing common errors related to ...

Uncertainty Quantification of Analytical Solutions for the Nonlinear Space and Time Fractional Order ϕ4$$ {\phi}^4 $$ Equation Under Fuzziness

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Finite Element Approximation for a Reformulation of a 3D Fluid–2D Plate Interaction System

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 4, July 2026.
ABSTRACT We study a finite element approximation of a coupled fluid‐structure interaction consisting of a three‐dimensional incompressible viscous fluid governed by the unsteady Stokes equations and a two‐dimensional elastic plate. To avoid the use of H2−$$ {H}^2- $$conforming or nonconforming ℙ2$$ {\mathbb{P}}_2 $$‐Morley plate elements, the fourth ...

Approximate Ricci‐Flat Metrics for Calabi–Yau Manifolds

open access: yesFortschritte der Physik, Volume 74, Issue 7, July 2026.
ABSTRACT We outline a method to determine analytic Kähler potentials with associated approximately Ricci‐flat Kähler metrics on Calabi–Yau manifolds. Key ingredients are numerically calculating Ricci‐flat Kähler potentials via machine learning techniques and fitting the numerical results to Donaldson's ansatz.
