与李代数滤子相关的可积系统

可精确求解与可积系统 2024-03-05 v4 群论 辛几何

摘要

1983年 Bogoyavlenski 猜想:若李代数 g0\mathfrak g_0 上的欧拉方程可积,则其对与李代数滤子 g0g1g2gn1gn=g\mathfrak g_0\subset \mathfrak g_1\subset \mathfrak g_2\dots\subset\mathfrak g_{n-1}\subset \mathfrak g_n=\mathfrak g 相关的半单李代数 g\mathfrak g 的某些扩张也可积。特别地,取 g0={0}\mathfrak g_0=\{0\}so(n)\mathfrak{so}(n)u(n)\mathfrak{u}(n) 的自然滤子,我们得到 Gel'fand-Cetlin 可积系统。我们证明了紧李代数 g\mathfrak g 滤子情形的猜想:该系统借助多项式积分在非交换意义下可积。文中还给出了该系统完备交换多项式积分的多种构造。
