Modified log-Sobolev inequalities and two-level concentration

open access: yes, 2020
We consider a generic modified logarithmic Sobolev inequality (mLSI) of the form $\mathrm{Ent}_{\mu}(e^f) \le \tfrac{\rho}{2} \mathbb{E}_\mu e^f \Gamma(f)^2$ for some difference operator $\Gamma$, and show how it implies two-level concentration ...

Generation of subordinated holomorphic semigroups via Yosida's theorem

open access: yes, 2014
Using functional calculi theory, we obtain several estimates for $\|\psi(A)g(A)\|$, where $\psi$ is a Bernstein function, $g$ is a bounded completely monotone function and $-A$ is the generator of a holomorphic $C_0$-semigroup on a Banach space, bounded ...

Statistical Convergence of Bernstein Operators

open access: yesApplied Mathematics & Information Sciences, 2016
The Bernstein operator is one of the important topics of approximation theory in which it has been studied in great details for a long time. The aim of this paper is to study the statistical convergence of sequence of Bernstein polynomials. In this paper, we introduce the concepts of statistical convergence of Bernstein polynomials and VB−summability ...

Approximation and Shape Preserving Properties of the Bernstein Operator of Max-Product Kind

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
Starting from the study of the Shepard nonlinear operator of max-prod type by Bede et al. (2006, 2008), in the book by Gal (2008), Open Problem 5.5.4, pages 324–326, the Bernstein max-prod-type operator is introduced and the question of the approximation

ψ‐Bernstein–Kantorovich operators

open access: yesMathematical Methods in the Applied Sciences
In this article, we introduce a modified class of Bernstein–Kantorovich operators depending on an integrable function and investigate their approximation properties. By choosing an appropriate function , the order of approximation of our operators to a function is at least as good as the classical Bernstein–Kantorovich operators on the interval .
