摘要：

The operator content of the exactly integrable models associated with the SU(N) Lie algebras, with periodic boundaries, are studied. The authors' results were obtained from a numerical and analytical analysis of the associated Bethe-ansatz equations. The resulting spectra indicate that the ferromagnetic and antiferromagnetic models have different operator content for N>2, being realizations of distinct modular invariant solutions.
