Wederive the underlying finite temperature theory which describes Fermi gassuperfluidity with population imbalance in a homogeneous system. We computethe pair formation temperature, superfluid transition temperature T_c, and superfluiddensity in a manner consistent with the standard ground stateequations and, thereby, present a complete phase diagram. Finite temperaturestabilizes superfluidity, as manifested by two solutions for T_c orby low T instabilities. At unitarity, the polarized state isan "intermediate-temperature superfluid."
