Elliptic solution for modified tetrahedron equations
As is known, tetrahedron equations lead to the commuting family of
transfer-matrices and provide the integrability of corresponding
three-dimensional lattice models. We present the modified version of these
equations which give the commuting family of more complicated two-layer
transfer-matrices. In the static limit we have succeeded in constructing the
solution of these equations in terms of elliptic functions.Comment: 11 page
Generalized Yang-Baxter Equation
A generalization of the Yang-Baxter equation is proposed. It enables to
construct integrable two-dimensional lattice models with commuting two-layer
transfer matrices, while single-layer ones are not necessarily commutative.
Explicit solutions to the generalized equations are found. They are related
with Botzmann weights of the chiral Potts model.Comment: 13 pages, TeX file. IHEP-93-?
