Abstract

We use umbral methods to obtain several general expansion theorems for linear operators and linear functionals. We show in particular that every linear operator admits Newton-type expansions. These expansions are prototypes of numerous classical ones as well as new ones, some of which are powerful enough for use in numerical approximation.
