FUNCTIONAL RELATIONS IN SOLVABLE LATTICE MODELS .2. APPLICATIONS

Reported are two applications of the functional relations (T system) among a commuting family of row-to-row transfer matrices proposed in the previous paper (Part I). For a general simple Lie algebra X(r), we determine the correlation lengths of the associated massive vertex models in the antiferroelectric regime and central charges of the RSOS models in two critical regimes. The results reproduce known values or even generalize them, demonstrating the efficiency of the T system.
