ON FORMULATIONS AND SOLUTIONS OF SIMPLEX EQUATIONS
J. Scott Carter, Masahico Saito · International Journal of Modern Physics A · 1996
A version of the tetrahedral equation is formulated using a pictorial interpretation of the Frenkel-Moore equation. The picture gives a solution that is a product of quantum Yang-Baxter solutions. Higher-dimensional variants of the Frenkel-Moore equations are found from this pictorial interpretation, and the pictures reduce their solvability to the solvability of lower-dimensional equations.
