On the Approximation Process of Shifted‐Knots Bivariate Stancu‐Type Kantorovich Operators

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper focuses on defining bivariate Stancu‐type Kantorovich operators with the technique associated with the idea of shifted knots. The degree of approximation and weighted approximation of these bivariate operators are estimated, respectively, by means of Lipschitz kind bivariate functions and weighted functions of two variables. Furthermore, the

Approximation properties of a bivariate Stancu type operator

Journal of Numerical Analysis and Approximation Theory, 2005
An extension of Stancu's operator \(P_{m}^{(\alpha ,\beta )}\) to the case of bivariate functions is presented and some approximation properties of this operator are discussed.

Shape-preserving and convergence properties of q-Stancu operator(q-Stancu算子的保形性及收敛定理)

Zhejiang Daxue xuebao. Lixue ban, 2009
给出了基于q-整数的Stancu算子Ln(•,q）,同时研究了该算子的一些基本性质.首先,利用q-Stancu算子作用于某一函数f(x)以后Ln(f,q;x)与f(x)变号数的关系,得到了该算子的保形性定理.其次,通过精细的不等式放缩,该算子作用于一般的连续函数后收敛于一极限算子,而不像一般算子那样收敛于函数本身,并用光滑模刻画了其收敛速度.

Chlodowsky variant of Bernstein-type operators on the domain

Open Mathematics
In the present paper, we deal with Bernstein-Chlodowsky type operators for approximating functions on the domain. We first present Bernstein-Chlodowsky type operators in two variables and then we discuss some examples of these operators under a domain ...

A Stancu type extension of the Cheney-Sharma Chlodovsky operators

Journal of Numerical Analysis and Approximation Theory
In this paper we introduce a Stancu type extension of the Cheney-Sharma Chlodovsky operators based on the ideas presented by Cătinaș and Buda, Bostanci and Bașcanbaz-Tunca, respectively Söylemez and Tașdelen.
