Y. Komori et K. Hikami, QUANTUM INTEGRABILITY OF THE GENERALIZED ELLIPTIC RUIJSENAARS MODELS, Journal of physics. A, mathematical and general, 30(12), 1997, pp. 4341-4364
The quantum integrability of the generalized elliptic Ruijsenaars mode
ls is shown. These models are mathematically related to the Macdonald
operator and the Macdonald-Koornwinder operator, which appeared in the
q-orthogonal polynomial theories. We construct these integrable famil
ies by using the Yang-Baxter equation and the reflection equation.
