On structure groups of set-theoretic solutions to the yang-baxter equation
This paper explores the structure groups G(X,r) of finite non-degenerate set-theoretic solutions (X,r) to the Yang-Baxter equation. Namely, we construct a finite quotient of G(X,r), generalizing the Coxeter-like groups introduced by Dehornoy for involutive solutions. This yields a finitary setting f...
