Summary

Many relations have been given connecting connecting the dispersion relations and frequency spectrum for a vibrating lattice. It is the purpose of this paper to show that these relations can all be derived from a single integral representation by using different representations of theδ-function.

Riassunto

Sono state formulate molte espressioni che mettono in rapporto le relazioni di dispersione con lo spettro di frequenza di un reticolo in vibrazione. È scopo di questo articolo mostrare che queste relazioni si possono tutte derivare da un’unica rappresentazione integrale usando diverse rappresentazioni della funzioneδ.
