Weighted approximation properties of Stancu type modification of q-Szász-Durrmeyer operators

In this paper, we are dealing with q-Sz·sz-Mirakyan-DurrmeyerStancu operators. Firstly, we establish moments of these operators and estimate convergence results. We discuss a Voronovska ja type result for the operators. We shall give the weighted approximation properties of these operators. Furthermore, we study the weighted statistical convergence for the operators.
