Ge. Arutyunov et al., ELLIPTIC RUIJSENAARS-SCHNEIDER MODEL FROM THE COTANGENT BUNDLE OVER THE 2-DIMENSIONAL CURRENT GROUP, Journal of mathematical physics, 38(11), 1997, pp. 5682-5689
It is shown that the elliptic Ruijsenaars-Schneider model can be obtai
ned from the cotangent bundle over the two-dimensional current group b
y means of the Hamiltonian reduction procedure. (C) 1997 American Inst
