Approximation properties of the new type generalized Bernstein-Kantorovich operators
AIMS Mathematics, 2022 In this paper, we introduce new type of generalized Kantorovich variant of α-Bernstein operators and study their approximation properties. We obtain estimates of rate of convergence involving first and second order modulus of continuity and Lipschitz ...

Matrix inequalities via Bernstein functions
Annals 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 ...

Quantum algorithms for testing Boolean functions [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 We discuss quantum algorithms, based on the Bernstein-Vazirani algorithm, for finding which variables a Boolean function depends on. There are 2^n possible linear Boolean functions of n variables; given a linear Boolean function, the Bernstein-Vazirani ...

Semi-Parametric Estimation Using Bernstein Polynomial and a Finite Gaussian Mixture Model
Entropy, 2022 The central focus of this paper is upon the alleviation of the boundary problem when the probability density function has a bounded support. Mixtures of beta densities have led to different methods of density estimation for data assumed to have compact ...

Quasi-linear dynamics of Weibel instability [PDF]
Annales Geophysicae, 2011 The quasi-linear dynamics of resonant Weibel mode is discussed. It is found that nonlinear saturation of Weibel mode is accompanied by substantial modification of the distribution function in resonant region.

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

Arab Journal of Mathematical Sciences, 2019 We give several new characterizations of completely monotone functions and Bernstein functions via two approaches: the first one is driven algebraically via elementary preserving mappings and the second one is developed in terms of the behavior of their ...

Bernstein-type operators that reproduce exponential functions [PDF]
Journal 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 ...
