%0 Journal Article %T Rational Calogero-Moser Model: Explicit Form and r-Matrix of the Second Poisson Structure %A Jean Avan %A Eric Ragoucy %J Symmetry, Integrability and Geometry : Methods and Applications %D 2012 %I National Academy of Science of Ukraine %X We compute the full expression of the second Poisson bracket structure for N=2 and N=3 site rational classical Calogero-Moser model. We propose an r-matrix formulation for N=2. It is identified with the classical limit of the second dynamical boundary algebra previously built by the authors. %K classical integrable systems %K hierarchy of Poisson structures %K dynamical reflection equation %U http://dx.doi.org/10.3842/SIGMA.2012.079
