K. Hikami et S. Murakami, INTEGRABILITY OF A HUBBARD-LIKE MODEL - LATTICE ANALOG OF THE DELTA-FUNCTION INTERACTING GAS, Physics letters. A, 221(1-2), 1996, pp. 109-114
The integrability of the one-dimensional Hubbard-like model proposed b
y Bariev is studied by using the representation of the affine Hecke al
gebra. The model is regarded as an integrable lattice analogue of the
delta-function interacting fermions.
