On an approximation operator and its Lipschitz constant


In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator.

We give a convergence theorem for this operator and we find its Lipschitz constant.
