摘要：

The nested Bethe ansatz is generalized to open boundary conditions. This is used to find the exact eigenvectors and eigenvalues of the A(n-1) vertex model with fixed open boundary conditions and the corresponding SU(q)(n)-invariant hamiltonian. The Bethe ansatz equations obtained are solved in the thermodynamic limit giving the vertex model free energy and the hamiltonian ground-state energy including the corresponding boundary contributions.
