The first Zolotarev case in the Erdös-Szegö solution to a Markov-type extremal problem of Schur

, 2017
Schur’s [14] Markov-type extremal problem asks to find the maximum (1) (2) (1)  sup  sup |Pn  (ξ)|, where Bn,ξ,2 = {Pn ∈ Bn : Pn  (ξ) = 0} ⊂ Bn =−1≤ξ≤1 Pn ∈Bn,ξ,2 {Pn : |Pn(x)| ≤ 1 for |x| ≤ 1} and Pn is an algebraic polynomial of degree ≤ n.

On global smoothness preservation by Bernstein-type operators

, 2015
We study global smoothness preservation of a function f by sequences of Bernstein-type operators with respect to a certain modulus of continuity of order two.

Global smoothness preservation and simultaneous approximation by multivariate discrete operators: Dedicated to Professor Gheorghe Coman on the occasion of his 80th anniversary

, 2016
In this article we study the multivariate generalized discrete singular operators defined on R N , N ≥ 1, regarding their simultaneus global smoothness preservation property with respect to Lp norm for 1 ≤ p ≤ ∞, by using higher order moduli of ...

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.

Q-deformed and λ-parametrized A-generalized logistic function induced Banach space valued multivariate multi-layer neural network approximations

Here we research the multivariate quantitative approximation of Banach space valued continuous multivariate functions on a box or RN, N ∈ N, by the multivariate normalized, quasi-interpolation, Kantorovich type and quadrature type neural network ...
