Abstract: I would like to describe recent results obtained together with M. Napiorkowski and inspired by an earlier work of R.Seiringer. We prove that the excitation spectrum of the Bose gas has the form predicted by the Bogoliubov approximation in an appropriate limit involving both the mean field and large volume approximation.
