Spin chain Hamiltonians with affine Uqg symmetry

We construct the family of spin chain Hamiltonians, which have affine Uqg quantum group symmetry. Their eigenvalues coincides with the eigenvalues of the usual spin chain Hamiltonians which have non-affine Uqg0 quantum group symmetry, but have the degeneracy of levels, corresponding to affine Uqg. The space of states of these chains are formed by the tensor product of the fully reducible representations.
