An Improved Material Point Method with Aggregated and Smoothed Bernstein Functions

open access: yesMathematics, 2023
Nodal shape functions and their gradients are vital in transferring physical information within the material point method (MPM). Their continuity is related to numerical stability and accuracy, and their support domain size affects computational ...

Matrix inequalities via Bernstein functions

open access: yesAnnals of Functional Analysis, 2022
The authors obtain a variety of matrix norm inequalities involving Bernstein functions, i.e., nonnegative, \(C^{\infty}\) functions defined on \((0, \infty)\), with completely monotone derivative. They prove that for \(f\) a Bernstein function, \(A,B\) positive definite matrices, \(X\) a complex matrix, all matrices of size \(n\times n\), we have ...

Better Uniform Approximation by New Bivariate Bernstein Operators

open access: yesInternational Journal of Analysis and Applications, 2022
In this paper we introduce new bivariate Bernstein type operators BnM,i(f; x, y), i = 1, 2, 3. The rates of approximation by these operators are calculated and it is shown that the errors are significantly smaller than those of ordinary bivariate ...

q-Completely monotonic and q-Bernstein functions [PDF]

open access: yesJournal of Applied Mathematics, Statistics and Informatics, 2014
Abstract We introduce the q-Bernstein functions, for 0<q<1 , and give sufficient and necessary conditions for a function to belong to the class of q -Bernstein functions. For some classes of functions we give results concerning q - completely monotonic and q -Bernstein functions.

On a New Generalization of Bernstein-Type Rational Functions and Its Approximation

open access: yesMathematics, 2022
In this study, we introduce a new generalization of a Bernstein-type rational function possessing better estimates than the classical Bernstein-type rational function.

Bernstein-type operators that reproduce exponential functions [PDF]

open access: yesJournal of Mathematical Inequalities, 2018
Summary: In this paper we recover a generalization of the classical Bernstein operators introduced by \textit{S. Morigi} and \textit{M. Neamtu} [Adv. Comput. Math. 12, No. 2--3, 133--149 (2000; Zbl 1044.42500)]. Specifically, we focus on a sequence of operators that reproduce the exponential functions \(\exp(\mu t)\) and \(\exp(2\mu t)\), \(\mu > 0 ...

On the local zeta functions and the b-functions of certain hyperplane arrangements

open access: yes, 2011
Conjectures of J. Igusa for p-adic local zeta functions and of J. Denef and F. Loeser for topological local zeta functions assert that (the real part of) the poles of these local zeta functions are roots of the Bernstein-Sato polynomials (i.e.

Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis

open access: yesArthritis Care &Research, EarlyView.
Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.
