Abstract

In the present paper we give quantitative type theorems for the differences of different bivariate positive linear operators by using weighted modulus of continuity. Similar estimates are obtained via K-functional and for Chebyshev functionals. Moreover, an example involving Szasz and Szasz-Kantorovich operators is given.

Keywords

Chebyshev functionals, bivariate positive linear operators, weighted modulus of continuity
