Definiamo relazioni canoniche discretizzate associate ad automorfismi di ordine finito di gruppi abeliani discreti. Questa è una generalizzazione di autoe Á morfismi di ordine finito di algebre di rotazione. Si dimostrano anche proprieta di particolari operatori di Schrödinger che derivano da queste relazioni.
