On differences of linear positive operators
(Springer Basel Ag, 2019)
In this paper we consider two different general linear positive operators defined on unbounded interval and obtain estimates for the differences of these operators in quantitative form. Our estimates involve an appropriate ...
On the generalized Picard and Gauss Weierstrass singular integrals
(Eudoxus Press, Llc, 2006)
In this paper, we give the generalizations of the Picard and the Gauss Weierstrass singular integral operators which are based on the q-numbers and depend on q-generalization of the Euler gamma integral. Later on, some ...
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 ...
Direct Estimates for Lupas-Durrmeyer Operators
(Univ Nis, Fac Sci Math, 2016)
The generalization of the Bernstein polynomials based on Polya distribution was first considered by Stancu [14]. Very recently Gupta and Rassias [6] proposed the Durrmeyer type modification of the Lupas, operators and ...
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 ...
Approximation properties of Szasz-Mirakyan operators preserving exponential functions
(Springer, 2019)
This paper is a natural continuation of Acar et al. (Mediterr J Math 14:6, 2017, 10.1007/s00009-016-0804-7) where Szasz-Mirakyan operators preserving exponential functions are defined. As a first result, we show that the ...
On Approximation Properties of a New Type of Bernstein-Durrmeyer Operators
(Walter De Gruyter Gmbh, 2015)
The present paper deals with a new type of Bernstein-Durrmeyer operators on mobile interval. First, we represent the operators in terms of hypergeometric series. We also establish local and global approximation results for ...
On approximation by some Bernstein-Kantorovich exponential-type polynomials
(Springer, 2019)
Since the introduction of Bernstein operators, many authors defined and/or studied Bernstein type operators and their generalizations, among them are Morigi and Neamtu (Adv Comput Math 12:133-149, 2000). They proposed an ...
Convergence of the q analogue of Szasz-Beta operators
(Elsevier Science Inc, 2010)
In the present paper we introduce the q analogue of the well known Szasz-Beta operators [11]. We also establish the approximation properties of these operators and estimate convergence results. In the end we propose an ...
Approximation by k-th order modifications of Szász-Mirakyan operators
(Akademiai Kiado Rt, 2016)
In this paper, we study the k-th order Kantorovich type modication of Szasz-Mirakyan operators. We first establish explicit formulas giving the images of monomials and the moments up to order six. Using this modification, ...
