(p,q) $(p,q)$-gamma operators which preserve x2 $x^{2}$

Abstract In this paper, we introduce (p,q) $(p,q)$-gamma operators which preserve x2 $x^{2}$, we estimate the moments of these operators, and establish direct and local approximation theorems of these operators. Then two approximation theorems about Lipschitz functions are obtained. The estimates on...
