Content
I will discuss a connection between the tetrahedron equation for maps
and the consistency property of integrable discrete equations on
$\mathbb{Z}^3$. The connection is based on the invariants of symmetry
groups of the lattice equations, generalizing a method developed in the
context of Yang-Baxter maps. The method will be demonstrated to certain
octahedron type lattice equations, leading to some new examples of
tetrahedron maps and integrable coupled lattice equations.
The talk is based on a joint work with Pavlos Kassotakis, Maciej
Nieszporski and Vassilis Papageorgiou.
