On the Bethe Ansatz Soluble Degenerate Hubbard Model

Studies of exactly soluble models for correlated electrons in one dimension have attracted wide spread interest in recent years. The reason for this is simple: they provide rigourous results on the behaviour of these systems in the presence of strong quantum fluctuations and thus may give some guidance at how to interpret observations in the much less well understood models in higher dimensions.
