Ge. Arutyunov et Sa. Frolov, ON THE HAMILTONIAN-STRUCTURE OF THE SPIN RUIJSENAARS-SCHNEIDER MODEL, Journal of physics. A, mathematical and general, 31(18), 1998, pp. 4203-4216
The Hamiltonian structure of the spin generalization of the rational R
uijsenaars-Schneider model is found by using the Hamiltonian reduction
technique. It is shown that the model possesses current algebra symme
try. The possibility of generalizing the obtained Poisson structure to
the trigonometric case is discussed and degeneration to the Euler-Cal
ogero-Moser system is examined.
