Integrability of a Hubbard-like model: lattice analogue of the \(\delta\)-function interacting gas
The integrability of the one-dimensional Hubbard-like model proposed by Bariev is studied by using the representation of the affine Hecke algebra. The model is regarded as an integrable lattice analogue of the \(\delta\)-function interacting fermions.
