Sunto
Si discutono due argomenti relativi alla teoria di sistemi interagenti di particelle che soddisfana alla statistica di Bose. Il primo concerne la struttura della funzione d’onda quantistica dello stato fondamentale ed il secondo le proprietà di un sistema di Bose in rotazione uniforme. L’enfasi è posta sulle proprietà di sistemi fortemente interagenti che rappresentano sperabilmente modelli realistici per l’elio liquido superfluido.
Summary
In this lecture we shall discuss two different topics in the theory of interacting Bose systems: the structure of its ground state wave function and the properties of this system in rotation. The emphasis will be on strongly interacting systems which are hopefully reasonably realistic models of liquid Helium Four.

Several arguments which support this contention are presented in reference 12; we have however not succeeded in proving the statement rigorously.
