How to find the Lax pair from the Yang-Baxter equation (Q1180366)

The authors give a brief description of the Yang-Baxter equations which play an important role in the theory of classical and quantum integrable systems. For a more fruitful application of the theory to the quantum case, a procedure for constructing the quantum Lax pair from the Yang- Baxter equations is required. By using an infinitesimal version of the Yang-Baxter equations, the authors describe an explicit procedure for constructing a quantum Lax pair. They illustrate their results by applying their procedure to study in some detail the Heisenberg XYZ model.
