Abstract
The possible classical limits of the SU(2)-invariant solution of the Yang-Baxter equation are systematically studied. In addition to the already known classical limits, namely the classical R-matrix, the lattice and the continuous L-operators, a series of new classical objects are introduced and the equations satisfied by them are enumerated.
