| Abstract: | We consider an integrable system with R-matrix related to the algebra sl
q(1 | 1). The Hamiltonian of the system is constructed, and its spectrum is found by means of the algebraic Bethe ansatz. The
symmetry algebra of the chain is written out. The partition function of the model on the lattice with domain wall boundary
conditions is calculated. Bibliography: 12 titles.
