Row transfer matrix functional relations for Baxterʹs eight-vertex and six-vertex models with open boundaries via more general reflection matrices Original Research Article

The functional relations of the transfer matrices of fusion hierarchies for six- and eight-vertex models with open boundary conditions have been presented in this paper. We have shown the su(2) fusion rule for the models with more general reflection boundary conditions, which are represented by off-diagonal reflection matrices. Also we have discussed some physics properties, which are determined by the functional relations. Finally, the intertwining relation between the reflection K-matrices for the vertex and SOS models is discussed.
