同一个非动力学r矩阵所对应的有理Ruijsenaars-Schneider模型(n=2)及Calogero-Moser模型

Rational Ruijsenaars-Schneider Models(n = 2) Governed by the Same Non-dynamical r-Matrix as in Calogero-Moser Ones

构造了有理 Ｒｕｉｊｓｅｎａａｒｓ－Ｓｃｈｎｅｉｄｅｒ模型（ｎ＝２）的新的 Ｌａｘ算子，发现相应的r矩阵是非动力学的，它与Ｃａｌｏｇｅｒｏ－Ｍｏｓｅｒ模型具有相同的r矩阵．

We gave a new Lax representation of rational Ruijsenaars-Schneider models(n = 2) which is governed by the same r-matrix as in Calogero-Moser model,and found that the corresponding r-matrix is non-dynamical.
