Description
In this paper, we study weighted approximation by bivariate generalized sampling series. Considering polynomially weighted spaces of bivariate functions we obtain pointwise and uniform convergence of the series. A rate of convergence is also presented by means of weighted modulus of continuity. In order to determine a rate of pointwise convergence, after estimating remainder of Taylor expansion of bivariate function with weighted modulus of continuity, we present a quantitative Voronovskaja theorem. Some numerical examples are also given.
