Khan, A.; Abbas, Z.; Qasim, M.; Mursaleen, M. Approximation by modified Lupaş-Stancu operators based on \((p, q)\)-integers. (English) Zbl 1488.41054 Eurasian Math. J. 12, No. 2, 39-51 (2021). Summary: The purpose of this paper is to construct a new class of Lupaş operators in the frame of post quantum setting. We obtain a Korovkin type approximation theorem, study the rate of convergence of these operators by using the concept of the \(K\)-functional and modulus of continuity, also give a convergence theorem for the Lipschitz continuous functions.
