Approximation Properties of Bivariate Extension of q-Bernstein–Schurer–Kantorovich operators

Abstract

In this paper, we introduce a bivariate generalization of the Bernstein–Schurer–Kantorovich operators based on q-integers and get a Bohmann–Korovkin type approximation theorem of these operators. We also estimate the rate of convergence of the proposed operators, in terms of the first modulus of smoothness.
