Abstract
We consider exactly solvable 1D multi-band fermionic Hamiltonians, whi ch have affine quantum group symmetry for all values of the deformatio n. The simplest Hamiltonian is a multi-band t - J model with vanishing spin-spin interaction, which is the affinization of an underlying XXZ model. We also find a multi-band generalization of standard t - J mod el Hamiltonian.
