Szasz Type Operators Involving Charlier Polynomials of Blending Type

摘要

We introduce a new sequence of linear positive operators by combining the Charlier polynomials and the Szasz type operators defined by Jain (in J Aust Math Soc 13(3):271-276, 1972). We obtain the degree of approximation of these operators by means of the weighted modulus of continuity and for functions in a Lipschitz type space. We also study the approximation of functions having a derivative equivalent with a function of bounded variation.
