On the monotonicity of $q$-Schurer-Stancu type polynomials

, 2018
Some properties of monotonicity and convexity of the q-Schurer -Stancu operators are considered. The paper contains also numerical examples based on Matlab algorithms, which verify these properties.

Local approximation behavior of modified SMK operators

, 2010
In this paper, for a general modification of the classical Szász–Mirakjan–Kantorovich operators, we obtain many local approximation results including the classical cases. In particular, we obtain a Korovkin theorem, a Voronovskaya theorem, and some local

Local and global results for modified Sz\'{a}sz - Mirakjan operators

, 2016
In this paper, we study a natural modification of Sz\'{a}sz - Mirakjan operators. It is shown by discussing many important established results for Sz\'{a}sz - Mirakjan operators.

The Bézier variant of Lupas Kantorovich operators based on Polya distribution

, 2018
In this paper we introduce the Bézier variant of Lupas Kantorovich operators based on Polya distribution. We establish a direct approximation by means of the Ditzian-Totik modulus of smoothness and a global approximation theorem in terms of second order ...

Approximation properties of bivariate extension of q-Szász-Mirakjan-Kantorovich operators

Journal of Inequalities and Applications, 2013
In the present paper, a bivariate generalization of the q-Szász-Mirakjan-Kantorovich operators is constructed by qR-integral and these operators’ weighted A-statistical approximation properties are established.

Note on a q-analogue of Stancu-Kantorovich operators

, 2015
The goal of this paper is to introduce new q-Stancu-Kantorovich operators and to study some of their approximation properties. A convergence theorem using the well known BohmanKorovkin criterion is proven and the rate of convergence involving the modulus

Fractional Trigonometric Korovkin Theory in Statistical Sense [PDF]

, 2010
2000 Mathematics Subject Classification: 41A25, 41A36.In the present paper, we improve the classical trigonometric Korovkin theory by using the concept of statistical convergence from the summability theory and also by considering the fractional ...

Certain approximation properties of Srivastava-Gupta operators

, 2018
In this paper we consider a modification of the well known sequence of summation integral operators, the Srivastava-Gupta operators, in order to achieve faster convergence for our operators over the classical ones.
