APPROXIMATION BY THE BIVARIATE COMPLEX BASKAKOV-STANCU OPERATORS
In this paper we study the approximation properties of the Stancutype bivariate generalization of the complex Baskakov operators. We obtaina Voronovskaja type result with quantitative estimates for bivariate complexBaskakov-Stancu operators attached to analytic functions having suitable exponential growth on compact polydisks. Also we give the exact order of approximation
