Dynamical r-matrix for the elliptic Ruijsenaars-Schneider system

Abstract

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 that was constructed in a recent paper manifest.Comment: 14 pages, LaTex, equations.sty, no figures, comment on explicit non-relativistic limit is adde
