introduction
- transfer matrix is builtup from matrices of Boltzmann weights
- trace of Monodromy matrix is the transfer matrix
- finding eigenvalues and eigenvectors of transfer matrix is crucial
- partition function = trace of power of transfer matrices
- so the partition function is calculated in terms of the eigenvalues of the transfer matrix
- then the problem of solving the model is reduced to the computation of this trace
Bethe ansatz
- Bethe ansatz equation is used to find the eigenvectors and eigenvalues of the transfer matrix
transfer matrix of the six-vertex model
