*"**Structure of the excitation spectrum for many-body quantum systems"*

**

/_Abstract:_////Many questions concerning models in quantum mechanics 
require a detailed analysis of the spectrum of the corresponding 
Hamiltonian, a linear operator on a suitable Hilbert space.
Of particular relevance for an understanding of the low-temperature 
properties of a system is the structure of the excitation spectrum, 
which is the part of the spectrum close to the spectral bottom.
We present recent progress on this question for bosonic many-body 
quantum systems with weak two-body interactions. Such system are 
currently of great interest, due to their experimental realization
in ultra-cold atomic gases. We investigate the accuracy of the 
Bogoliubov approximations, which predicts that the low-energy spectrum 
is made up of sums of elementary excitations,
with linear dispersion law at low momentum. The latter property is 
crucial for the superfluid behavior the system.///
