Here we state a quantitative approximation theorem by means of nets of certain modified Hadamard integrals, using iterates of moment type operators, for functions defined over the positive real semi-axis, having Mellin derivatives. The main tool is a suitable K-functional. Some numerical examples and graphical representations are illustrated.

Abstract
Here we state a quantitative approximation theorem by means of nets of certain modified Hadamard integrals, using iterates of moment type operators, for functions defined over the positive real semi-axis, having Mellin derivatives. The main tool is a suitable K-functional. Some numerical examples and graphical representations are illustrated.File in questo prodotto:
