Abstract :
In this paper we introduce the (p, q) -analogue of the Stancu-Beta operators
and call them as the (p, q)-Stancu-Beta operators. We study approximation properties
of these operators based on the Korovkin’s approximation theorem and also study some
direct theorems. Also, we study the Voronovskaja type estimate for these operators.
