Abstract
A toy model of strongly correlated fermions is studied using Green fun ction and functional integration methods. The model exhibits a metal-i nsulator transition as the interaction is varied. In the case of unres tricted hopping an equivalence of the model with the Hubbard model wit h infinite range hopping is established. The generalization to the cas e with N components is made.
