Abstract
Using the Frohlich Hamiltonian, we obtain self-consistent equations fo r the energy gap and the chemical potential. Using these equations, ry e can analyze the superconductivity properties of the system for an ar bitrary carrier concentration. We consider weak, intermediate, and str ong interactions between fermions and observe the transition from the Cooper coupling to the local-pair regime in the indirect-interaction m odel.
