On King type modification of $(p,q)$-Lupaş Bernstein operators

Abstract

In this paper, a King-type modification of (p, q)-Lupaş Bernstein operators are introduced. The rate of convergence of these operators are studied by means of modulus of continuity and Lipschitz class functional. Further, it has been shown that the error estimation of these operators on some subintervals of [0, 1] are better than the (p, q)-Lupaş Bernstein operators.
