某些具有代数起源和分离变量的可积系统

Some integrable systems of algebraic origin and separation of variables

O. K. Sheinman

摘要:

一条平面代数曲线,其牛顿多边形含有d个格点,可以由它所通过的d个点给出。然后将其方程Poisson交换的系数视为这些点坐标的函数。在O.Babelon和M.Talon 2002年的工作中观察到。我们制定了一个概括这一事实的分离变量和证明关系隐含的泊松交换性。用这种方法得到的可积系统的例子包括Lagrange和Hermit插值多项式的系数、Weierstrass曲线模型的系数。

英文摘要:

A plane algebraic curve whose Newton polygone contains d lattice points can be given by d points it passes through. Then the coefficients of its equation Poisson commute having been regarded as functions of coordinates of those points. It is observed in the work by O.Babelon and M.Talon, 2002. We formulate a generalization of this fact in terms of separation of variables and prove relations implying the Poisson commutativity. The examples of the integrable systems obtained this way include coefficients of the Lagrange and Hermit interpolation polynomials, coefficients of the Weierstrass models of curves.
