Some approximation results by (p, q)-analogue of Bernstein–Stancu operators.

In this paper, we introduce a new analogue of Bernstein–Stancu operators based on ( p, q )-integers which we call as ( p, q )-Bernstein–Stancu operators. We study approximation properties for these operators based on Korovkin’s type approximation theorem and also study some direct theorems. Furthermore, we give comparisons and some illustrative graphics for the convergence of operators to some function. [ABSTRACT FROM AUTHOR]
