Direct Estimates for Stancu Variant of Lupaş-Durrmeyer Operators Based On Polya Distribution

[摘要] In this paper, we study approximation properties of a family of linear positive operators and establish the Voronovskaja type asymptotic formula, local approximation and pointwise estimates using the Lipschitz type maximal function. In the last section, we consider the King type modification of these operators to obtain better estimates.
