Fw. Nijhoff et al., DYNAMICAL R-MATRIX FOR THE ELLIPTIC RUIJSENAARS-SCHNEIDER SYSTEM, Journal of physics. A, mathematical and general, 29(13), 1996, pp. 333-340
The classical r-matrix structure for the generic elliptic Ruijsenaars-
Schneider model is presented. It makes manifest the integrability of t
his model as well as of its discrete-time version that was constructed
in a recent paper.
