Better Approximation Properties by New Modified Baskakov Operators
This paper introduces a new idea to obtain a better order of approximation for the Baskakov operator. We conclude two new operators from orders one and two of the Baskakov type. Also, we prove some directed results concerning the rate of convergence of these operators.

Polynomial approximations to continuous functions and stochastic compositions [PDF]
This paper presents a stochastic approach to theorems concerning the behavior of iterations of the Bernstein operator $B_n$ taking a continuous function $f \in C[0,1]$ to a degree-$n$ polynomial when the number of iterations $k$ tends to infinity and $n$

Ideal relatively uniform convergence with Korovkin and Voronovskaya types approximation theorems
We introduce the notion of ideally relative uniform convergence of sequences of real valued functions. We then apply this notion to prove Korovkin-type approximation theorem, and then construct an illustrative example by taking (p,q)-Bernstein operators which proves that our Korovkin theorem is stronger than its classical version as well as

Approximation Properties of Complex q-Gamma operators and a Equivalent Condition of (p,q)-integers [PDF]
本文主要研究以下两个方面的内容: (1)在复空间上研究复q-Gamma算子对解析函数的同时逼近阶和Voronovskaya型逼近定理; (2)通过举出反例证明Mursaleen等人得到的(p,q)-算子的收敛性定理是错误的,并给出了一个(p,q)-整数趋于无穷的等价条件.This paper mainly focuses on the following two aspects of content: (1) The order of simultaneous approximation and ...

Modified double Szász-Mirakjan operators preserving $x^{2}+y^{2}$ [PDF]
In this paper, we introduce a modification of the Sz\u27{a}sz-Mirakjan type operators of two variables which preserve $f_{0}left( x,yright) =1$ and $% f_{3}left( x,yright) =x^{2}+y^{2}.$ We prove that this type of operators enables a better error ...

On the Generalized Baskakov Durrmeyer Operators
The main object of this paper is to construct Baskakov Durrmeyer type operators such that their construction depends on a function ρ. Using the weighted modulus of continuity, we show the uniform convergence of the operators. Moreover we obtain pointwise

The Lower Estimate for Bernstein Operator [PDF]
MSC 2010: 41A10, 41A15, 41A25, 41A36For functions belonging to the classes C2[0; 1] and C3[0; 1], we establish the lower estimate with an explicit constant in approximation by Bernstein polynomials in terms of the second order Ditzian-Totik modulus of ...

The current paper deals with a modified form of the Baskakov–Schurer–Szasz–Stancu operators which preserve e−2ax $e^{-2ax}$ for a>0 $a>0$. The uniform convergence of the modified operators is shown.

Generalized Szász-Mirakian Type Operators [PDF]
In this paper, we are proposing certain modifications of Szász-Mirakian type operators and study their approximation properties. We also give a Voronovskaya type theorem for these operators.
