Abstract
Nuclear pairing field is investigated within the framework of functional integrals. The equations of motion for the quasiparticles are obtained, in the presence of dynamic and static mean fields, using the stationary phase approximation. Small fluctuations of the pairing fields around their mean values are considered. In the limit of static mean fields, the stationary phase contribution to energy together with the leading term of quadratic corrections reproduces the Hartree-Fock-Bogoliubov energy of the quasi-particle vacuum state.
