A note on the eight tetrahedron equations
Jarmo Hietarinta, Frank Nijhoff
In this paper we derive from arguments of string scattering a set of eight tetrahedron equations, with different index orderings. It is argued that this system of equations is the…

Permutation-type solutions to the Yang-Baxter and other n-simplex equations
Jarmo Hietarinta
We study permutation type solutions to n-simplex equations, that is, solutions whose R matrix can be written as a product of delta- functions depending linearly on the indices. Wit…

On the parametrization of solutions of the Yang--Baxter equations
J. Hietarinta, C. Viallet
We study all five-, six-, and one eight-vertex type two-state solutions of the Yang-Baxter equations in the form , and analyze the inte…
