Approximation by (p, q)-Lupas-Schurer-Kantorovich operators

In the current paper, we examine the (p,q)-analogue of Kantorovich type Lupa Schurer operators with the help of (p,q)-Jackson integral. Then, we estimate the rate of convergence for the constructed operators by using the modulus of continuity in terms of a Lipschitz class function and by means of Peetre's K-functionals based on Korovkin theorem. Moreover, we illustrate the approximation of the (p,q)-Lupa Schurer Kantorovich operators to appointed functions by the help of Matlab algorithm and then show the comparison of the convergence of these operators with Lupa Schurer operators based on (p,q)-integers.
