The family of Szász-Durrmeyer Type Operators Involving Charlier Polynomials

Naokant Deo, Ram Pratap

In this paper, we consider Szász-Durrmeyer type operators based on Charlier polynomials associated with Srivastava-Gupta operators \cite{SG:03}. For the considered operators, we discuss error of estimation by using first and second order modulus of continuity, Lipchtiz-type space, Ditzian-Totik modulus of smoothness, Voronovskaya type asymptotic formula and weighted modulus of continuity.
