In questo articolo trattiamo lo sviluppo storico del concetto di funzione reale computabile. Durante il XX secolo alcune scuole hanno proposto approcci alternativi alla questione, ma in generale tra loro strettamente correlati. Tuttavia, mettiamo in risalto come i due paradigmi TTE a real-RAM, traendo origine da due differenti rami della matematica (teoria della computabilità ed analisi numerica) abbiamo elaborato due approcci contrastanti.
In this paper we deal with the historical development of the notion of computable real function. During the XX century, some mathematical schools provided different approaches to the subject, which are in general strictly related. Nevertheless, we point out how the two paradigms TTE and real-RAM have formulated two incompatible approaches. This contrast is mainly due to their own two different theoretical foundations (computer science on the one hand and numerical analisis on the other).
