In a recent paper [3] C. Baiocchi, V. Komornik and P. Loreti obtained a generalisation of Parseval's identity by means of divided differences. We give here a proof of the optimality of that theorem.
In un lavoro recente [3] C. Baiocchi, V. Komornik e P. Loreti hanno ottenuto una generalizzazione dell'identità di Parseval utilizzando delle differenze divise. Noi dimostriamo l'ottimalità del loro teorema.
