Bosonic Structure of a 2Dimensional Fermion Model with Interaction among Different Species II  Nspecies Case 
Abstract
We study a massive Thirringlike model in 2dimensional spacetime, which contains fermions with arbitrary number (N) of different species. This model is an extension of that of a previous paper, where we have considered twospecies case. By this extension we expect that we can expose more general structures of this kind of model. We obtain the equivalent boson model with N species to our fermion model. We find that the coupling constant must be set in some regions in order for the model to be physically sensible. It seems hard to find such regions from direct obsavation of the original fermion model. We also find that for specific values of the coupling constant some of the boson fields disappear from the system. Therefore, the Nspecies fermion model is described by the boson model with fewer species.
