“…Motivated by the FRT construction of a q-analogue of the function space [7,8], one of the author constructed Hopf algebroids A σ [15,32,33] by means of dynamical Yang-Baxter maps σ [14,18,19,20,25,28,29,30,31]. This σ is a set-theoretic solution to a version of the quantum dynamical Yang-Baxter equation [9,10], a generalization of the quantum Yang-Baxter equation [2,3,37,38].…”
