Abstract
The generator-coordinate method, well known in nuclear physics, is employed to derive the Bogoliubov theory of superfluidity of a boson system. The treatment is fully number conserving. Analogies to a normal Fermi system (especially to the random-phase approximation for that system) are pointed out, and some further insight into the nature of superfluidity is gained. Possible generalizations are mentioned.Keywords
