Abelian fixed point free endomorphisms and the Yang-Baxter equation (2020)
Journal Article
Koch, A., Stordy, L., & Truman, P. J. (2020). Abelian fixed point free endomorphisms and the Yang-Baxter equation

We obtain a simple family of solutions to the set-theoretic Yang-Baxter equation, one which depends only on considering special endomorphisms of a finite group. We show how such an endomorphism gives rise to two non-degenerate solutions to the Yang-B... Read More about Abelian fixed point free endomorphisms and the Yang-Baxter equation.
