Abstract

The paper is centered on the study of a class of linear positive operators of discrete type introduced in 1983 by D. D. Stancu. These operators depend on a non-negative integer parameter r and on two real parameters α, β. In this note we use the divided differences as fundamental mathematical tools in the investigation of the monotonicity properties of this class of operators.
