摘要：
The two-dimensional Hubbard model is studied by use of composite operator approach. A set of self-consistent equations for the fermion propagator is derived in a generalized mean held approximation. Preliminary results show a good agreement with the exact results obtained by numerical simulation on finite sie lattices.
