Modified Baskakov-Szász Operators Based on q-Integers

Abstract

In the present paper we introduce the Stancu variant of certain q-modified Baskakov \(Sz\acute{a}sz\) operators. We estimate the moments of the operators and obtain some direct results in terms of the modulus of continuity. Then, we study the Voronovskaja type theorem and the rate of convergence of these operators in terms of the weighted modulus of continuity. Further, we discuss the point-wise estimation using the Lipschitz type maximal function. Finally, we investigate the rate of statistical convergence of these operators using weighted modulus of continuity.
