摘要
The finite-size corrections for the free energy of the two-sublattice vertex model which are defined on the infinitely long lattice of finite width N are calculated on the basis of the Bethe ansatz equations for the diagonal to diagonal transfer matrix. It is shown that the finite-size corrections confirm the prediction of the theory of conformal invariance. The conformal anomaly number obtained is C = 1. © 1990.
