我们显式构造了额外的运动积分,确保了离散时间有理Ruijsenaars-Schneider模型的最大超可积性。利用这些积分,我们研究了连续和离散时间背景下超可积性的代数方面。特别地,我们确定了与有理Ruijsenaars-Schneider模型及其离散化相关的多项式对称代数的完整结构。我们证明了离散化导致连续对称代数相对于离散化参数的非平凡变形,从而将最近从有理Calogero-Moser系统得到的类似结果推广到其相对论性推广。
英文摘要
We explicitly construct the additional integrals of motion, ensuring maximal superintegrability of the discrete-time rational Ruijsenaars-Schneider model. Using them, we investigate the algebraic aspects of superintegrability in both continuous- and discrete-time settings. In particular, we determine the complete structures of the polynomial symmetry algebras associated with both the rational Ruijsenaars-Schneider model and its discretization. We demonstrate that discretization leads to a nontrivial deformation of the continuous symmetry algebra with respect to the discretization parameter, thereby extending recent analogous results from the rational Calogero-Moser system to its relativistic generalization.
