Some approximation results for (p, q)-Lupaş-Schurer operators


K Kanat, M Sofyalıoğlu




In this paper, we introduce Lupaş-Schurer operators based on (p, q)-integers. Then, we deal with the approximation properties for (p, q)-Lupaş-Schurer operators based on Korovkin type approximation theorem. Moreover, we compute rate of convergence by using modulus of continuity, with the help of functions of Lipschitz class and Peetre's K-functionals.
