Korovkin type theorem in the space $C_{b}[0,\infty)$: Dedicated to Professor Gheorghe Coman on the occasion of his 80th anniversary

, 2016
A Korovkin type theorem is established in the space $C_{b}[0,\infty)$ of all continuous and bounded functions on $[0,\infty)$ for a sequence of positive linear operators, the approximation error being estimated with the aid of the usual modulus of ...

Approximation with an arbitrary order by generalized Kantorovich-type and Durrmeyer-type operators on [0, +∞)

, 2017
Given an arbitrary sequence λn > 0, n ∈ N, with the property that limn→∞ λn = 0 as fast we want, in this note we introduce modified/ gene- ralized Sza´sz-Kantorovich, Baskakov-Kantorovich, Sza´sz-Durrmeyer-Stancu and Baskakov-Sza´sz-Durrmeyer-Stancu ...

Eigenstructure of the genuine Beta operators of Lupaș and Mühlbach: Dedicated to Professor Gheorghe Coman on the occasion of his 80th anniversary

, 2016
The eigenstructure of genuine Beta operators is described, a limiting case of Beta-Jacobi operators. Its similarity to that of the classical Bernstein operators is emphasized.

Overiteration of d-variate tensor product Bernstein operators: A quantitative result (Dedicated to the memory of Professor Sorin Gal)

Extending an earlier estimate for the degree of approximation of over iterated univariate Bernstein operators towards the same operator of degree one, it is shown that an analogous result holds in the d-variate case.

Multivariate Voronovskaya type asymptotic expansions for normalized bell and squashing type neural network operators

, 2012
Here we introduce the multivariate normalized bell and squashing type neural net-work operators of one hidden layer. We derive multivariate Voronovskaya type asymptotic expansions for the error of approximation of these operators to the unit operator ...

Approximation of fractional derivatives by Brass-Stancu operators

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we study uniform approximation of fractional derivatives in Caputo sense by Brass-Stancu operators. For the rate of approximation, we give some estimates in terms of the modulus of continuity.
