On certain family of mixed summation integral type two-dimensional qq-Lupaş–Phillips–Bernstein operators

In the present paper, we introduce a two dimensional mixed summation–integral type qq-Lupaş–Phillips–Bernstein operators on a rectangular domain □=[0,1]×[0,1]□=[0,1]×[0,1] and investigate their Korovkin type approximation properties. We compute the rate of convergence of these new operators by means of the full and partial modulus of continuity. We also establish the order of approximation for the operators by using the Peetre K-functional. In last section, we get some numerical examples for operator.
