Reflections and Drinfeld twists for set-theoretic Yang-Baxter maps
Davide Ferri
The Yang-Baxter equation (YBE) and the reflection equation (RE) both come from mathematical physics, and they can be defined in any monoidal category. For cartesian monoidal catego…

Structure groupoids of quiver-theoretic Yang-Baxter maps
Davide Ferri, Youichi Shibukawa
Solutions to the quiver-theoretic quantum Yang-Baxter equation are associated with structure categories and structure groupoids. We prove that the structure groupoids of involutive…
