A new class of generalized polynomials associated with Hermite and Bernoulli polynomials

open access: yesLe Matematiche, 2015
In this paper, we introduce a new class of generalized  polynomials associated with  the modified Milne-Thomson's polynomials Φ_{n}^{(α)}(x,ν) of degree n and order α introduced by  Derre and Simsek.The concepts of Bernoulli numbers B_n, Bernoulli ...

Novel Approximate Solutions for Nonlinear Blasius Equations

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
The method of operational matrices based on different types of polynomials such as Bernstein, shifted Legendre and Bernoulli polynomials will be presented and implemented to solve the nonlinear Blasius equations approximately. The nonlinear differential

Anticipatory, Chronic, and Imminent: A Typology of Insecurities Underlying Protracted Conflict Displacement and Its Implications

open access: yesPopulation and Development Review, EarlyView.
Abstract Protracted armed conflicts increasingly drive long‐term displacement, yet demographic frameworks often treat forced migration from conflict settings as a response to acute, singular events. This study introduces a typology of displacement grounded in the tempo and form of conflict‐related insecurities—anticipatory, chronic, and imminent—and ...

On a conjecture of S. Chowla and of S. Chowla and H. Walum, I

open access: yes, 1985
As an extension of the Dirichlet divisor problem, S. Chowla and H. Walum conjectured that, as x → ∞, Σn ≤ √x naBr({xn}) = O(xa2 + 14 + ε) holds for each ε > 0. Here integers a ≥ 0 and r ≥ 1 are given.

On the q-Lie group of q-Appell polynomial matrices and related factorizations

open access: yesSpecial Matrices, 2018
In the spirit of our earlier paper [10] and Zhang and Wang [16],we introduce the matrix of multiplicative q-Appell polynomials of order M ∈ ℤ. This is the representation of the respective q-Appell polynomials in ke-ke basis.

Scalable Approximation of the Transformation‐Free Linear Simplicial–Simplicial Regression via Constrained Iterative Reweighted Least Squares

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Simplicial–simplicial regression concerns statistical modeling scenarios in which both the predictors and the responses contain vectors constrained to lie on the simplex. Fiksel et al. introduced a transformation‐free linear regression framework for this setting, wherein the regression coefficients are estimated by minimizing the Kullback ...

A kind of improved bivariate even order Bernoulli-type multiquadric quasi-interpolation operator and its application in two-dimensional coupled Burgers’ equations

open access: yesBoundary Value Problems
Multiquadric quasi-interpolation is an efficient high-dimensional approximation algorithm. It can directly obtain the approximation term and its derivatives without solving any large-scale linear equations.

A Note on Bernoulli Numbers and Shintani Generalized Bernoulli Polynomials [PDF]

open access: yesTransactions of the American Mathematical Society, 1996
Generalized Bernoulli polynomials were introduced by Shintani in 1976 in order to express the special values at non-positive integers of Dedekind zeta functions for totally real numbers. The coefficients of such polynomials are finite combinations of products of Bernoulli numbers which are difficult to get hold of.
