In this paper, we deal with the complex Baskakov-Szsz-Durrmeyer mixed operators and study Voronovskaja type results with quantitative estimates for these oper
Let P(z) be a polynomial of degree n and for any complex number α, let Dα P(z) = n P(z)+(α-z)P′(z) denote the polar derivative of P(z) with respect to α. I
