This parametrization is based on the solution of the associated classical discrete integrable system. Using a three-dimensional vertex satisfying a modified tetrahedron equation, we construct an operator which generalizes the BS quantum intertwining matrix . This operator describes the isospectral deformations of the integrable BS model.200510.1088/0305-4470/38/33/0052015-12-11
