On the classical limits of the $SU(2)$-invariant solutions to the Yang-Baxter equation

All the possible classical limits of the $SU(2)$-invariant solution to the quantum Yang–Baxter equation are systematically studied. In addition to the already known classical limits: the classical $r$-matrix, the lattice and continuous $L$-operators, some new classical objects are introduced and the equations satisfied by them are enlisted.
