椭圆曲线与可积系统的一种新构造

Elliptic Curves and a New Construction of Integrable Systems

Vladimir Dragovic, Borislav Gajic

摘要:

研究了一类具有Lax矩阵的椭圆曲线.构造了一类具有上述Lax矩阵的多项式a参数化的e(3)上的动力系统.在保留标准测量值的条件下,从该家系中选取5例.其中三个是哈密尔顿的。证明了另外两种情况在e(3)上的标准Poisson结构中不是Hamilton的。证明了所有五种情况的可集成性。在所有五种情况下都进行了整合程序。也给出了Sklyanin意义下的分离变量。建立了与Hess-Appel'rot系统的联系。本文对Hess-Appel'rot系统提出了一种分离变量的方法。

英文摘要:

A class of elliptic curves with associated Lax matrices is considered. A family of dynamical systems on e(3) parametrized by polynomial a with above Lax matrices are constructed. Five cases from the family are selected by the condition of preserving the standard mea- sure. Three of them are Hamiltonian. It is proved that two other cases are not Hamiltonian in the standard Poisson structure on e(3). Integra- bility of all five cases is proven. Integration procedures are performed in all five cases. Separation of variables in Sklyanin sense is also given. A connection with Hess-Appel'rot system is established. A sort of sep- aration of variables is suggested for the Hess-Appel'rot system.
