Abstract

In the present paper, we show that a subclass of the operators defined by Lupaș [12] preserve properties of the modulus of continuity function and Lipschitz constant and the order of a Lipschitz continuous function. We are also concerned with the monotonicity of a sequence of such operators for convex functions.
