Abstract: 
We consider the lowdensity limit of a Fermi gas in the BCS approximation. We show that if the interaction potential allows for a twoparticle bound state, the system at zero temperature is well approximated by the GrossPitaevskii functional, describing a BoseEinstein condensate of fermion pairs.
