A toy model of strongly correlated fermions is studied using Green function\nand functional integration methods. The model exhibits a metal-insulator\ntransition as the interaction is varied. In the case of unrestricted hopping is\nestablished the equivalence of the model with the Hubbard model with infinite\nrange hopping. The generalization to the case with N components is made.\n
