Stancu Curves in CAGD [PDF]

Journal of Numerical Analysis and Approximation Theory, 2002
Starting from the one-parameter dependent linear polynomial Stancu operator, we consider the related polynomial curve scheme with one scalar shape parameter.

On a generalization of the Stancu-Schurer operator of higher order

Journal of Numerical Analysis and Approximation Theory
In this paper, we introduce a generalization of the higher-order Stancu–Schurer operator. Starting from a particular form of the operator recently introduced by the authors, we extend the convex combination of two terms appearing in its expression to a ...

Approximation properties of two dimensional Bernstein-Stancu-Chlodowsky operators [PDF]

Le Matematiche, 2013
In this paper, as a generalization of Bernstein-Stancu type operators of two variable, we introduce a new positive linear operator called Bernstein-Stancu-Chlodowsky on a triangular domain, with mobile boundaries, which extends to [0, ∞) × [0, ∞) as n → ∞

On a compound approximation operator of D.D. Stancu type [PDF]

Journal of Numerical Analysis and Approximation Theory, 2006
In this note we consider a linear and positive compound approximation operator of D.D. Stancu type depending of several parameters; we give the expressions of this operator on the test functions, the conditions under which this operator converges to a ...

On Kantorovich variant of Brass-Stancu operators

Demonstratio Mathematica
In this study, we deal with Kantorovich-type generalization of the Brass-Stancu operators. For the sequence of these operators, we study Lp{L}^{p}-convergence and give some upper estimates for the Lp{L}^{p}-norm of the approximation error via first-order

On the eigenstructure of the q-Stancu operator [PDF]

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics
The main goal of this research is to find the eigenvalues and the corresponding eigenfunctions of the q-Stancu operator, $L_{n,s,q}$, introduced by $L$. Yun and R. Wang. In this work, an explicit representation for moments of all orders has been derived.

Stancu modified operators revisited [PDF]

Journal of Numerical Analysis and Approximation Theory, 2002
In this paper we construct a general positive approximation process representing an integral form in Kantorovich sense of the Stancu operators. By using K-functionals and some moduli of smoothness we give direct theorems for pointwise approximation.
