Abstract
The problem of calculating the eigenvalues of the transfer matrix for exactly solvable quantum systems is considered. A new analytical method is proposed. The method is applied to the O(n)-invariant magnet model and to the Izergin-Korepin model, some anisotropic generalization of the SU(3)-invariant magnet.
