SOME RESULTS CONCERNING MASTROIANNI OPERATORS BY POWER SERIES METHOD

Abstract

In this paper, we consider power series method which is also member of the class of all continuous summability methods. We study a Korovkin type approximation theorem for the Mastroianni operators with the use of power series method which includes Abel and Borel methods. We also give some estimates in terms of the modulus of continuity and the second modulus of smoothness.
