Durrmeyer-Type Bernstein Operators Based on (p, q)-Integers with Two Variables

摘要

The purpose of this study is to introduce the Durrmeyer-type Bernstein operators based on (p, q)-integers with two variables. Then, we compute the error of approximation by using modulus of continuity and the degree of approximation by means of Lipschitz class. Finally, we obtain the numerical results in detail.
