review text: The authors consider two lattice models for strongly correlated electrons, where the weak coupling \(\nu\rightarrow 0\) limit of the first model is not described by free electrons while the second model describes free electrons. The first model exhibits an itinerant ferromagnetic behaviour, while for the other the electrons form bound pairs and at half-filling the model becomes insulating. The authors derive the termodynamic Bethe ansatz equations for the models, analyze them at various limits, and in particular obtain a zero temperature phase diagram.
