Kuznetsov, V. B.; Tsyganov, A. V. Quantum relativistic Toda chain. (Russian. English summary) Zbl 0821.17026 Zap. Nauchn. Semin. POMI 205, 71-84 (1993). The relativistic Toda chain, which is a generalization of a classical periodic Toda chain, is studied. A description of the model in terms of Lax triads is given. This gives a possibility to prove complete integrability and define local integrals of motion. On the other hand, an inverse scattering method is developed, and a quantum analog of the system with standard trigonometric \(R\)-matrix is defined. Sklyanin’s program of separation of variables is realized both in the classical and quantum cases. The corresponding spectral problem is written down explicitly. All the results are generalized to the case of integrable boundary conditions of \(B\), \(C\), \(D\) types.
