Here we give a Voronovskaja formula for linear combination of Mellin-Picard type convolution operators, using the Mellin-Picard kernel. This approach provides a better order of pointwise approximation. Some applications are described.

Abstract
Here we give a Voronovskaja formula for linear combination of Mellin-Picard type convolution operators, using the Mellin-Picard kernel. This approach provides a better order of pointwise approximation. Some applications are described.File in questo prodotto:
