Exactly Solvable IRF Models. III. A New Hierarchy of Solvable Models
Yasuhiro Akutsu, Atsuo Kuniba, Miki Wadati
An infinite series of exactly solvable multi-state IRF models is constructed. Each model in the new hierarchy is the special S 2 -generalization, proposed in the previous paper II, of the corresponding model in the `eight-vertex SOS' hierarchy. The Boltzmann weights and their parametrizations are given with a detailed proof that they satisfy the star-triangle equation.
