The work is motivated by the numerousfascinating experiments which, in the last decade, have been carried out in the field of dilute ultra coldatomic gases.In order to cover both normal and super fluid phase we extend the many body formalism devel oped by Luttinger and Ward and by DeDominicis and Martin.
