We explore the consequences of coupling between repulsive Hubbard models and Bosonic or spin degrees of freedom. In the regime where the characteristic energy of the non-fermionic part is large compared to the characteristic energy of the Fermions, the effective Hamiltonian corresponds to a generalized attractive Hubbard model. Superconducting properties are then calculated within the BCS scheme including the finite size dependence of correlation functions functions characterizing s-wave pairing. © 1990 Springer-Verlag.
