Bivariate Cheney-Sharma operators on simplex

Abstract

In this paper, we consider bivariate Cheney-Sharma operators which are not the tensor product construction. Precisely, we show that these operators preserve Lipschitz condition of a given Lipschitz continuous function $f$ and also the properties of the modulus of continuity function
when $f$ is a modulus of continuity function.

Keywords

• Lipschitz continuous function,modulus of continuity function,bivariate Cheney-Sharma operators
