Simultaneous approximation by a class of Bernstein-Durrmeyer operators preserving linear functions
Heiner Gonska,Radu Păltănea +1 more
TL;DR: In this article, a one-parameter class of positive linear operators constituting a link between the well-known operators of S.N. Bernstein and their genuine Bernstein-Durrmeyer variants are studied.

Quantitative convergence theorems for a class of Bernstein–Durrmeyer operators preserving linear functions
Heiner Gonska,Radu Păltănea +1 more
TL;DR: In this paper, the authors supplement recent results on a class of Bernstein-Durrmeyer operators preserving linear functions by discussing two limiting cases and proving quantitative Voronovskaya-type assertions involving the first-order and second-order moduli of smoothness.

General Voronovskaya and Asymptotic Theorems in Simultaneous Approximation
Heiner Gonska,Radu Păltănea +1 more
TL;DR: In this article, general asymptotic and Voronovskaya theorems for simultaneous approximation were proved for the Durrmeyer and Bernstein operators, as well as for the Bernstein operator.
Journal ArticleDOI
Optimal estimates with moduli of continuity
TL;DR: In this paper, the authors obtained estimates with optimal constants for the pointwise approximation of functions by linear positive functional, with the aid of a new second order modulus with a parameter.
