H. Fan et al., INTEGRABLE BOUNDARY-CONDITIONS ASSOCIATED WITH THE Z(N)XZ(N) BELAVIN MODEL AND SOLUTIONS OF REFLECTION EQUATION, International journal of modern physics A, 12(16), 1997, pp. 2809-2823
We construct solvable models with nontrivial boundary from the well kn
own Belavin R-matrix. The reflection equation for the boundary reflect
ion matrix is studied and the complete solution for the one associated
with the eight-vertex model is found.
