We generalize the SU(2|2) supersymmetric extended Hubbard model of 1/r2interaction to the SU(m|n) supersymmetric case. Integrable models may bedefined on both uniform lattice and non-uniform one dimensional lattices. Westudy both cases in detail and present the ground state wavefunctions andenergy spectra of these models.Comment: 24 pages, Late
