Direct and converse theorems for King type operators
For a sequence of King type operators which preserve the functions \begin{document}$ e_0(x)=1 $\end{document} and \begin{document}$ e_j(x)=x^j $\end{document}, we establish a direct approximation theorem via the first order Ditzian-Totik modulus of ...

Blending type approximation by Stancu-Kantorovich operators based on Pólya-Eggenberger distribution
In the paper the authors introduce the Kantorovich variant of Stancu operators based on Pólya-Eggenberger distribution. By making use of this new operator, we obtain some indispensable auxiliary results.

The family of Szász-Durrmeyer Type Operators Involving Charlier Polynomials
In this paper, we consider Szász-Durrmeyer type operators based on Charlier polynomials associated with Srivastava-Gupta operators [17]. For the considered operators, we discuss error of estimation by using first and second order modulus of continuity ...

Nonparametric estimation of the mixing density using polynomials [PDF]
We consider the problem of estimating the mixing density $f$ from $n$ i.i.d. observations distributed according to a mixture density with unknown mixing distribution.

Approximation degree of Durrmeyer–Bézier type operators
Recently, a mixed hybrid operator, generalizing the well-known Phillips operators and Baskakov–Szász type operators, was introduced. In this paper, we study Bézier variant of these new operators.

Lp‐Approximation (p ≥ 1) by q‐Kantorovich Operators
For a new q‐Kantorovich operator we establish direct approximation theorems in the space Lp[0,1], 1 ≤ p ≤ ∞, via Ditzian‐Totik modulus of smoothness of second order.

Some Approximation Properties of q‐Baskakov‐Beta‐Stancu Type Operators
This paper deals with new type q‐Baskakov‐Beta‐Stancu operators defined in the paper. First, we have used the properties of q‐integral to establish the moments of these operators. We also obtain some approximation properties and asymptotic formulae for these operators. In the end we have also presented better error estimations for the q‐operators.

Some approximation properties of ( p , q ) $(p,q)$ -Bernstein operators
This paper is concerned with the ( p , q ) $(p,q)$ -analog of Bernstein operators. It is proved that, when the function is convex, the ( p , q ) $(p,q)$ -Bernstein operators are monotonic decreasing, as in the classical case.
