Abstract

Abstract : In this study, it is proposed to define bivariate Chlodowsky variant of( p, q ) -Bernstein-Stancu-Schurer operators. Therefore, Korovkin-type approximation theorems and the error of approximation by using full modulus of continuity are presented. Beside this, we introduce a generalization of the bivariate Chlodowsky variant of( p, q ) -Bernstein-Stancu-Schurer operators and investigate its approximation in more general weighted space. Moreover, the numerical results are discussed in order to validate the accuracy of the bivariate Chlodowsky variant of( p, q ) -Bernstein-Schurer operators.
