Dynamical r-matrix for the elliptic Ruijsenaars-Schneider system
F. W. Nijhoff, V. B. Kuznetsov, E. K. Sklyanin +1
The classical r-matrix structure for the generic elliptic Ruijsenaars-Schneider model is presented. It makes the integrability of this model as well as of its discrete-time version…

Integrable Time-Discretisation of the Ruijsenaars-Schneider Model
F. W. Nijhoff, O. Ragnisco, V. B. Kuznetsov
An exactly integrable symplectic correspondence is derived which in a continuum limit leads to the equations of motion of the relativistic generalization of the Calogero-Moser syst…
