Bézier variant of the Szász-Durrmeyer type operators based on the Poisson-Charlier polynomials


Arun Kajla, Dan Miclăuş




In the present paper we introduce the Bézier variant of the Szász-Durrmeyer type operators, involving the Poisson-Charlier polynomials. Our study focuses on a direct approximation theorem in terms of the Ditzian-Totik modulus of smoothness and the rate of convergence for differential functions whose derivatives are of bounded variation.
