We show that the Yang-Baxter equations for two dimensional models admit as a group of symmetry the infinite discrete group A (1) 2. The existence of this symmetry explains the presence of a spectral parameter in the solutions of the equations. We show that similarly, for three-dimensional vertex models and the associated tetrahedron equations, there also… CONTINUE READING
