Sunto
Si espongono ricerche e risultati sulla classica questione della esistenza, e delle eventuali proprietà, della funzione distribuzione di una funzione additiva o moltiplicativa.
Si accenna anche ad alcune questioni connesse, quali quella della densità dei numeri abbondanti primitivi.
L’esposizione si chiude con una elencazione di problemi tuttora aperti che si possono prospettare in questo campo di ricerche.
Summarx
In this paper researches and results about the existence and properties of the distribution function of an additive function are illustrated. Some associated questions are also considered; for example the density of primitive abundant numbers.
The paper ends with an enumeration of unsolved problems which can be encountered in these researches.

A simple argument shows that if the conditiontj ≥ai is replaced bytj ≥0 the logarithmic density in question does not always exist.
