Noncommutative solutions to Zamolodchikov's tetrahedron equation and matrix six-factorisation problems
Sotiris Konstantinou-Rizos
Abstract:It is known that the local Yang-Baxter equation is a generator of potential solutions to Zamolodchikov's tetrahedron equation. In this paper, we show under which additional conditions the solutions to the local Yang-Baxter equation are tetrahedron maps, namely solutions to the set-theoretical tetrahedron equation. This is exceptionally useful when one wants to prove that noncommutative maps satisfy the Zamolodchikov's tetrahedron equation. We construct new noncommutative maps and we prove that they possess the… Show more
