On discrete Picard operators
(Wiley-Blackwell, 2016)
The present paper is concerned with the approximation properties of discrete version of Picard operators. We first give exact equalities for the moments of the operators. In calculations of these moments, Eulerian numbers ...
(p, q)-Type Beta Functions Of Second Kind
(Tusi Mathematical Research Group, 2016)
In the present article, we propose the (p, q)-variant of beta function of second kind and establish a relation between the generalized beta and gamma functions using some identities of the post-quantum calculus. As an ...
The new forms of Voronovskaya's theorem in weighted spaces
(Springer, 2016)
The Voronovskaya theorem which is one of the most important pointwise convergence results in the theory of approximation by linear positive operators (l.p.o) is considered in quantitative form. Most of the results presented ...
Power series of Beta operators
(Elsevier Science Inc, 2014)
In this paper we investigate the power series of Beta operators. We first study the convergence of this series and describe the Voronovskaya operator A and the inverse Voronovskaya operator. Then, a quantitative convergence ...
Weighted Approximation by New Bernstein-Chlodowsky-Gadjiev Operators
(Univ Nis, Fac Sci Math, 2013)
In the present paper, we introduce Bernstein-Chlodowsky-Gadjiev operators taking into consideration the polynomials introduced by Gadjiev and Ghorbanalizadeh [2]. The interval of convergence of the operators is a moved ...
On the q analogue of Stancu-Beta operators
(Pergamon-Elsevier Science Ltd, 2012)
In the present work we introduce the q analogue of well known Stancu-Beta operators. We estimate moments and establish direct results in terms of the modulus of continuity. We also present an asymptotic formula. (C) 2011 ...
A Voronovskaya-type formula for SMK operators via statistical convergence
(Versita, 2011)
In this paper, we obtain a statistical Voronovskaya-type theorem for the Szasz-Mirakjan-Kantorovich (SMK) operators by using the notion of A-statistical convergence, where A is a non-negative regular summability matrix.
Approximation by q Baskakov Beta operators
(Springer Heidelberg, 2011)
In the present paper we introduce the q analogue of the Baskakov Beta operators. We establish some direct results in the polynomial weighted space of continuous functions defined on the interval [0, a). Then we obtain ...
Some approximation properties of q-Baskakov-Durrmeyer operators
(Elsevier Science Inc, 2011)
Very recently Aral and Gupta [1] introduced q analogue of Baskakov-Durrmeyer operators. In the present paper we extend the studies, we establish the recurrence relations for the central moments and obtain an asymptotic ...
On the Durrmeyer type modification of the q-Baskakov type operators
(Pergamon-Elsevier Science Ltd, 2010)
This paper deals with Durrmeyer type generalization of q-Baskakov type operators using the concept of q-integral, which introduces a new sequence of positive q-integral operators. We show that this sequence is an approximation ...
