Gamma variant of (p, q) -Bernstein type novel operators [PDF]

Journal of Hyperstructures
In this paper, we are concerned with a new modification of the well-known (p;q)-Bernstein novel type operators with the gamma integral functions. The direct results demonstrate several aspects of approximations.

Holmstedt's formula for the K‐functional: the limit case θ0=θ1$\theta _0=\theta _1$

Mathematische Nachrichten, Volume 296, Issue 12, Page 5474-5492, December 2023., 2023
Abstract We consider K‐interpolation spaces involving slowly varying functions, and derive necessary and sufficient conditions for a Holmstedt‐type formula to be held in the limiting case θ0=θ1∈{0,1}$\theta _0=\theta _1\in \lbrace 0,1\rbrace$. We also study the case θ0=θ1∈(0,1)$\theta _0=\theta _1\in (0,1)$.

Approximation by bivariate generalized Bernstein–Schurer operators and associated GBS operators

Advances in Difference Equations, 2020
We construct the bivariate form of Bernstein–Schurer operators based on parameter α. We establish the Voronovskaja-type theorem and give an estimate of the order of approximation with the help of Peetre’s K-functional of our newly defined operators ...

Quantitative estimates for a certain bivariate Chlodowsky-Szasz-Kantorovich type operators [PDF]

, 2016
In this paper, we introduce a bivariate Kantorovich variant of the combination of Chlodowsky and Szasz type operators and study local approximation properties of these operators.

A new kind of variant of the Kantorovich type modification operators introduced by D. D. Stancu

Results in Applied Mathematics, 2021
In the present article we investigate a variant of the Kantorovich type modification defined by Kajla (2018) i.e. we introduce a function ζ(ϰ)in the operators defined by Kajla (2018) s.t.

A note on real interpolation of Hardy spaces in the polydisk

, 1986
The atomic decomposition for the Hardy spaces H p {H^p} of the product of upper half-spaces is used to characterize Peetre’s K K -functional for two such spaces.

Some approximation results on Chlodowsky type q−Bernstein-Schurer operators

, 2023
The main concern of this article is to obtain several approximation features of the new Chlodowsky type q-Bernstein-Schurer operators. We prove the Korovkin type approximation theorem and discuss the order of convergence with regard to the ordinary ...
